Bomboclat, also spelled bomboclaat or bumboclaat, comes from Jamaican patois, where it developed from a literal term for a cloth into a strong slang exclamation for shock, anger or excitement. It spread globally through reggae and dancehall culture, then took on a second life online in 2019 when Twitter users paired the word with unrelated images as a caption meme. Short shouted versions like this one later circulated on TikTok, in meme edits and on soundboards as a quick reaction sound.
