BOP

BOP shows a cartoon mallet landing on a smiling head. The command describes both the action and its comic sound: a `bop` is a quick light hit, so the typed word and the image deliver the same slapstick beat.

Twitch communities later folded BOP into the wider "bonk, go to horny jail" meme. Because the emote already showed a hammer strike, it became a ready-made visual reprimand when a streamer or chat became conspicuously thirsty, while still working for ordinary playful bonks.

Viewers type BOP in Twitch chat for a playful bonk, a harmless "knock it off" reaction, a horny-jail joke, or another comic impact moment.
