誤爆 (gobaku, “accidental explosion”) Means “Wrong Chat” in Japanese Slang

Definition of Gobaku

Originally, 誤爆 (ごばく, gobaku) means “accidental explosion/bombing”. As a slang word, however, it also means “Opps, wrong chat”, i.e. the act of inadvertently sending a message to a wrong chat/person. This fiasco usually takes place on a messaging app like LINE/Messenger, and the accident on LINE is called “LINE  誤爆”, for instance. It could also happen on social media like Twitter when you have multiple accounts and behave like a different person in each account. A common example of it is when famous people inadvertently share a post about their very private life (e.g. photos of their secret partner) on their official account instead of their private/secret one.

Gobaku on Purpose

Apparently, some people do “fake gobaku” to confess their feelings to their crush. Let’s say you have a crush on a girl named Ana; to reveal your feelings for her, you send her a “wrong chat” such as “I’m so in love with Ana! Do you know whether she has a boyfriend?”, pretending that you’ve “accidentally” sent the message to her instead of your friend. While some websites recommend this as an “effective approach” to have your crush interested in you, many people clearly find it quite obvious, awkward and pathetic.
