The phrase translates from French as asking who all these idiots are, and the clip circulates online mainly as a short reaction sound rather than as a line tied to a widely documented film, show or viral video. Its exact original recording is not clearly documented, so its popularity rests on the wording and delivery rather than a famous source. French-speaking meme creators use it to puncture absurd behaviour, while other users share it for its tone alone, which helps explain why a clip lasting barely over a second keeps appearing in edits, reaction videos and soundboards.
