The line comes from Les Visiteurs, the popular French comedy about medieval visitors lost in the modern world, where 'arrêtez de gueuler' means 'stop yelling.' French-speaking creators lifted the short shouted line for reaction videos and gaming streams because it is instantly recognizable and funnier than a plain 'shut up.' It now circulates on soundboards and in memes as a playful scolding, especially in French TikTok edits and Twitch clips where someone is being deliberately loud.
