Quoicoubeh is a viral French internet slang term that exploded on TikTok in early 2023, primarily popularized by the creator Cams (La Vache). The term functions as a linguistic trap; when someone asks 'Quoi?' (What?), the joker immediately responds with 'Quoicoubeh!' to confuse or annoy the listener. It is part of a broader trend of nonsense words used by French-speaking youth, alongside similar terms like 'Apanyae.' While the word has no literal definition, it has become a defining symbol of Gen Alpha humor, often used in videos to prank teachers, parents, or peers. On social media, the meme is frequently depicted through reaction images or videos where the 'victim' looks baffled while the prankster celebrates their successful wordplay.
