40 Funny Japanese Old Slang Words to Sound like Oyaji (Old Men)

Do you fancy Japanese slang words and want to learn something very “deep“? Then it’s time to learn Japanese old, classic slang words and phrases (i.e. 死語しご, “dead words”)! Well, probably you might question the necessity of learning *old-fashioned* expressions, but I can tell you that it’s a lot of fun to learn the history of Japanese and sees how its trend has changed over the decades! In addition, some of the expressions are still used deliberately by some people to make jokes or act as stereotypical aged/old-fashioned people, especially on social media such as Twitter.

In what follows, I introduce old-fashioned slang words based on their categories. First, I start with slang expressions with 逆さかさ読よみ (reading words in reverse order; back slang), which represent the “bubbly” and auspicious era in the late 1980s, when Japan’s over-inflated economy reached its pinnacle.

* I don’t want to scare you away, but this post is definitely one of the most outlandish articles on this website, so be careful about when and where to use these expressions below (you probably don’t wanna use them in a job interview, or when you meet someone for the first time)! 

“Back Slang” in Japanese

In the late 1980s, it was once a trend among people in the TV industry to create their jargons by reading words in (partially) reverse order. Eventually, these “back slang words” spread to ordinary people after some celebrities (esp. a comedy duo とんねるず) had started to use them on TV shows.  Although most of them are now quite old-fashioned, some people still use them as a joke or humorous expression.

Here is the list of famous “back slang” words and phrases; see more details (pronunciations and example sentences) at  my previous post “ザギンでシースー: 12 Japanese “Reverse” Slang Words From 1980s”

(All of the words are written in katakana here, but hiragana is also fine.)

ザギン means 銀座 (ぎんざ), “Ginza”

ギロッポン means 六本木 (ろっぽんぎ, “Roppongi”)

シース means 寿司 (すし), “sushi”.

“ギロッポン/ザギンでシース” means “to eat sushi in Roppongi/Ginza”, and is one of the most famous “back slang” phrases. Roppongi and Ginza are one of the most lucrative cities in Japan, and some people (esp. those in the TV industry) presumably employed these expressions to make their dinner plan sound more special and prestigious.

パイオツ means おっぱい, “tit”

カイデー means でかい, “big”.

チャンネー means “ねーちゃん” (“older sister/girl/chick”)

“パイオツカイデーなチャンネー” means “a chick with big tits”, and is one of the most famous back slang phrases.

メンゴ means ごめん “sorry”, and is often used as “メンゴメンゴ”, meaning “Soz soz” to apologise in a very casual way.

クリソツ means “そっくり” (“very alike/exactly look like ~”)

シャレオツ means お洒落 (おしゃれ) (“fashionable”); this word is less outdated than the others, and is still used among some young people at times.

しもしも means もしもし (“Hello?” ; an expression Japanese people use when they answer the phone.)

Expressions With a Pun

This section introduces old-fashioned expressions that make a pun in themselves. These are very effective expressions to use when you want to deliberately sound very lame or old-fashioned.

ワケワカメ

ワケワカメ is a joking way of saying 訳わけがわからない meaning “I don’t understand at all”. ワカメ (wakame) is a type of edible seaweed popular in Japan, and it is used as a substitute for “わからない” in this phrase.

アイムソーリー ヒゲソーリー

アイムソーリーヒゲソーリー is an old-fashioned famous pun in Japanese. The first part “アイムソーリー” means “I’m sorry” and the second part “ヒゲソーリー” means “ひげ剃そり”, i.e. “a razor”. Some people also add the name of Prime Minister (総理, そうり) afterwards to make another pun with ソーリー, as in “アイムソーリー ヒゲソーリー安倍あべソーリー”.

許ゆるしてちょんまげ

許してちょんまげ is a very non-serious way of saying “許してちょうだい” meaning “Please forgive me”.  ちょんまげ means a top-knot hairstyle of samurai, and it is used as a substitute for “ちょうだい” meaning “please” in this phrase.

当あたり前まえだのクラッカー

当たり前だのクラッカー is a joking way of saying “当たり前だ” meaning “of course” or “(something is) very obvious”. The latter part “のクラッカー” is added to make a pun with the name of the traditional Japanese snack “前田まえだのクラッカー (Maeda’s cracker)”. This phrase gained its popularity after it was used in the TV commercials of the product in 1960s.

エッチスケッチワンタッチ

This rhyming phrase consists of three words “エッチ” (“sexually naughty”), スケッチ (“sketch”) and ワンタッチ (“one-touch”). It doesn’t quite have a specific meaning or usage, but is something that we have said or heard somewhere in our childhood.

そんなバナナ

そんなバナナ is a jocular way of saying “そんなバカな” meaning “No way!” or “That can’t be true”. As you see, バナナ (“banana”) is used as a substitute for “バカな” in this phrase.

冗談じょうだんはよしこちゃん

冗談はよしこちゃんis a joking way of saying “冗談じょうだんはよして”, meaning “please stop kidding”. よしこちゃん is “Yoshiko-chan”, i.e. the girl’s name “Yoshiko” with the Japanese honorific “chan” attached.

余裕よゆうのよっちゃん

余裕のよっちゃんmeans “easy-peasy/a piece of cake”, where 余裕よゆう means “very easy” and よっちゃん is a common nickname for someone whose name starts from よ, e.g. よしこ (, which means nothing here, like “peasy” in “easy-peasy”.)

Combination of Two words

This section introduces old slang words that are coined by combining two different words.

飲のみにケーション

飲みにケーション means “communication through drinking together”. It combines two words “飲む” (“drink”) and コミニケーション (“communication”). Some (old-fashioned) people insist that 飲みにケーション be indispensable to build a “real” relationship (, which explains why many Japanese people go for drinks with their boss and colleagues after work, and sleep like a log on the train to home.)

バイナラ

バイナラ means “bye-bye/see you”. It combines two words “バイバイ” (bye-bye) and “さよなら” (“sayonara”).

ダイジョウVぶい

ダイジョウV is a joking way of saying “大丈夫 (だいじょうぶ)” meaning “I’m fine/no problem”. It combines “大丈夫” with ブイ (“V”), which adds a casual (and nowadays lame) tone to the word.

すいま千円せんえん, すいませんべい

すいま千円 is a joking way of saying “すいません” meaning “I’m sorry”. It combines すいません with 千円せんえん (1000 yen) or せんべい (Japanese rice crackers) for no reason.

いただきマンモス

いただきマンモス is a joking way of saying “いただきます”, an expression to show your gratitude for the food before you eat it. It combines いただきます with マンモス “mammoth” for no reason.

Loanwords (mainly from English)

This section introduces old-fashioned slang words based on foreign languages (mainly English).

チョベリバ, チョベリグ

チョベリバ and チョベリグ are slang terms that used to be popular among female teenagers in the late 1990s (Nowadays, these words are often used to mock these people back then.) The words stand for “超ベリーバッド” and “超ベリーグッド” resp., where 超 means “extremely/super” and ベリーバッド/ベリーグッド are clearly loaned from “very bad/good” in English. Therefore, it means “super very bad/good” (quite redundant indeed, but sort of mitigated by the abbreviated form).

OK牧場ぼくじょう

OK牧場 means “OK/no problem”, which used to be frequently said by a former boxing world champion ガッツ石松. Usually, “牧場” means “a farm”, but it means nothing in this phrase (like “Dokey” in “Okey-Dokey”).

アベック

アベック is a very old-fashioned word meaning “a couple”. It is loaned from the French word “avec”, meaning “with” (as in, a couple always does things with each other).

おニュー

おニュー means “brand new”, where ニュー is loaned from “new” in English and “お” is an honorific prefix. In the Kansai area, its synonym (in terms of the meaning, tone and obsolescence) is “さらぴん“, a derivative of the more standard Kansai dialect word “さら”, meaning “new”.

ナウい

ナウい means “new/trendy/fashionable” and comes from the English term “now”. However, this word itself does not sound new anymore (although it is still well recognised as one of the outdated slang terms).

タンマ

タンマ means “hold on/one moment”, which is loaned from “time” in English. Usually, it is used as “ちょっとタンマ” (“hold on a bit”), where ちょっと means “a bit”.

トゥギャザーしようぜ

トゥギャザーしようぜ means “Let’s do (something) together”, and is coined by a Japanese comedian ルー大柴, who often makes jokes by combining Japanese and English words in his speech (as in this phrase).

ヤング

ヤング means “young people”, and it is often used as “ナウなヤング” or “ナウいヤング”  meaning “fashionable/trendy young people”

アウトオブ眼中がんちゅう

アウトオブ眼中 is an old-fashioned way of saying “眼中がんちゅうにない, which literally means “not in my eyes” and figuratively means “I don’t care at all/don’t give a sh*t”. It combines the English phrase “out of ~” and the Japanese word “眼中” meaning “in one’s eyes”.

グー, バッチグー

グー and バッチグー mean “good” and “very good”, respectively. Here, グー is short for グッド, and バッチ is short for ばっちり, meaning “perfect(ly)”.

Others

３Kけー, ３高こう

３K and３高, meaning “three high”, stand for “高学歴こうがくれき、高身長こうしんちょう、高収入こうしゅうにゅう“, which literally means “high education background, high height, and high salary”. This word used to be popular among girls to describe their ideal men who are highly educated (e.g. go to a high-level university),  very tall (e.g. over 180 cm), and have a high-salary job. Although this word has become obsolete per se, the popularity of such men has never ever faded away, of course. In fact, people nowadays use another term, “ハイスペック” (“high-spec”) or “ハイスペ” in short,  to describe those attractive men. However, compared to ３K or ３高, ハイスペック is more gender-neutral and used by both men and women to describe people who have impressive skills and careers.

ガーン, がびーん

ガーン and がびーん are both exclamations which you say when you are disappointed/shocked in a bad way (e.g. when you know you failed an exam). It is still used sometimes in manga or anime (e.g. ちびまる子ちゃん), but rarely heard in real life anymore.

ヨロピク

ヨロピク is a joking way of saying “よろしく”, a very common Japanese greeting which you use when they ask someone to do something, or when you show your willingness to build a good relationship with someone.

かわい子こちゃん

かわい子ちゃん means “cute girls/cuties”. Here, かわい子 is short for “かわいい子 (cute girl)”, and ちゃん is a Japanese honorific used for children and girls.

ドロンする

ドロンする is a very old-fashioned word that means “go home/leave/disappear”. It used to be frequently said in the expression, “お先さきにドロンします“, meaning “Excuse me, I’m leaving now (earlier than you)”.

イケイケ

イケイケ means “energetic/lively/active” or “cool/cute/hot”. It can describe both things and people, as in “イケイケな時代じだい” (lively/positive era) and “イケイケな人” (energetic, active, cool person).

バカウケ

バカウケ means “funny like crazy”, where バカ means “stupid/crazy” and ウケ is short for ウケる meaning “funny/is found funny by …”. For instance, ヤングにバカウケなギャグ means “a joke/gag found crazy funny by young people/a joke that makes young people laugh like crazy”.

花金はなきん 

花金 means “Happy Friday” or “TGIF” and is often used when people go for a drink on Friday after work. Although it is usually regarded as an outdated word, some people still use it as there is no other term to describe the joy of drinking on Friday night. For instance, you can say “今日は花金だし、飲もう” meaning “Since today’s 花金, let’s drink!”.

インド人じんもびっくり

インド人もびっくり literally means “Indian people are also surprised”. This expression became popular in the 1960s once it was used in the TV commercials of Japanese curry roux to hype it as “Even Indian people are amazed by the taste”. Therefore, as a parody, you can use this phrase to describe something nice, or simply to show your surprise at something.

モチのロン

モチのロン is a humorous and old-fashioned way of saying もちろん, meaning “of course”. Although it can read as “モチ’s ロン”, neither モチ nor ロン does not make any sense here.

うれぴー

うれぴー is a casual way of saying  “嬉うれしい (happy)”. When you are super happy, you can say マンモスうれぴー, where マンモス (“mammoth”) is figuratively used to describe the humungous amount of happiness. These phrases were coined by a famous actress 酒井法子 (Noriko Sakai), a.k.a. のりぴー in late 1980. Although she was arrested in 2009 on drugs charges, she has returned to the media committee after a long period of suspension.

マブダチ

マブダチ means “real friend” or “best friend”, where ダチ is short for 友達ともだち (friend).

社会しゃかいの窓まど

社会の窓 literally means “the window of the society”, but actually refers to “the fly of trousers”. It is used as “社会の窓が開あいてますよ” (“The window of the society is open”) when you tell someone (esp. men) in a humorous way that their fly is open.

A Funny Song about Outdated Slang Words

“ナウなヤングにバカウケするのは当あたり前まえだのクラッ歌か“

To help you remember those classic Japanese slang words, I introduce a very unique Japanese song called “ナウなヤングにバカウケするのは当あたり前まえだのクラッ歌か“, wrote and sung by the popular Japanese singer-songwriter あいみょん (Aimyon). This song features a variety of Japanese old-fashioned expressions, most of which are covered in this article. First of all, as you see, the title already contains four old slang words: ナウな (trendy/new), ヤング (young people), バカウケ (very funny), 当たり前だのクラッ歌か (a modified version of “当たり前田のクラッカー”; 歌 means “song”).

Here is the link to the YouTube video:

(And you can check the whole lyric here or here.)

If you like this song, there are a great number of beautiful songs made and sung by あいみょん; I’d like to conclude this article by sharing some of my favourite songs of hers with the links to her official YouTube videos!

マリーゴールド

This is the most popular song of hers in terms of the number of views on YouTube (more than 200 Million views). This is quite a nice song to listen to, especially in summer!
