Introduction
Definition of Portmanteau Words
Before diving into the word list, let’s clarify the definition of portmanteau words first. Portmanteau words are the words that combine parts of multiple words, such as brunch (“breakfast” + “lunch“) and stagflation (“stagnation” + “inflation“). In Japanese, portmanteau is translated as かばん語 (kabango, “bag word”), but since it is a technical term used in linguistics only, it is rarely recognised/understood by Japanese people (I’ve never heard anyone saying this word before).
Portmanteau vs. Compound Words
Portmanteau words differ from compound words, which combine multiple complete words without truncation; one example is teaspoon, which concatenates two words “tea” and “spoon”. I’ve explained Japanese compound words in the separate post below (e.g. 猫舌 (ねこじた, nekojita) meaning “cat tongue”, if you’re interested!
Portmanteau vs. Abbreviated Words
While this is not discussed on most websites that provide a list of portmanteus, portmanteau words can be classified into two types depending on whether they are an abbreviation of a phrase or not. For instance, brunch is not an abbreviation of the phrase “breakfast lunch”, but rather a new word that originated from them. On the other hand, webinar is an abbreviation of the phrase “web seminar”, which is used by itself in a sentence. Brexit (British + exit) is a somewhat ambiguous case, as the original phrase also makes sense by itself and is used in the same meaning. However, it would probably be more of a new word than an abbreviation, given that Brexit is much more commonly used than the original phrase.
In Japanese, abbreviation of words/phrases is very common, to the extent that there are thousands of them, e.g. 就活 (shūku) for 就職活動 (shūshoku katsudou) meaning “job-hunting activities”. This is particularly true of proper nouns and English loanwords, which include 東大 (toudai) for 東京大学 (toukyou daigaku, “The University of Tokyo”), ポケモン (Pokémon) for “Pocket Monsters”, and セクハラ (sekuhara) for セクシャルハラスメント (“sexual harrasment”). Therefore, I’ve decided to introduce such abbreviated expressions in a separate post below and focus on the unabbreviated ones here — even though both of them fall under the umbrella of portmanteau words. Therefore, the focus of this post is on the portmanteau words that combine (parts of) multiple words that are usually not used together as a phrase.

いただきます (itadakimasu) + マンモス (“mammoth”)
Meaning
Same as いただきます, a Japanese phrase to say before eating food to express one’s appreciation. マンモス (“mammoth”) has zero meaning here except for making a pun. This phrase is clearly outdated; see the previous post to learn more outdated (and bizarre) Japanese slang.
Example

Meaning
“super awesome/awful”; this word often represents outdated slang words that used to be popular among teen gals in the 1990s.
(Example sentences are omitted, as I’m not entirely sure how to use them properly… It seems it was often used as an exclamation, like “awesome!”)
