The phrase is French slang for telling someone to shut up, which gives this short Futurama clip its instant punch even for viewers who only recognise the tone. Shared as a compact reaction sound, it travels well between French-speaking meme pages and wider short-form video, where a one-second interruption fits a punchline better than a longer quote. Its appeal is its bluntness: it sounds like a cartoon character finally snapping, so creators keep reaching for it whenever a conversation needs a fast, rude full stop.
