Feur is a French internet joke built around answering the question quoi with a single playful word, and it is closely associated online with creator TheoBabac. The gag spread through short videos and reaction clips, where the word itself became the punchline rather than part of a longer sentence. Its appeal comes from simplicity and timing: anyone who knows the joke recognises it instantly, while newcomers hear a sharp, unexpected reply. That shared recognition keeps it circulating in French meme edits and playful comment replies.
