The phrase is French slang that roughly translates to asking what those idiotic noises are, and the clip has circulated mainly as a TikTok reaction sound. Its exact original source is not widely documented, so its popularity comes from reuse rather than a known film or show. Creators lift the shout to caption moments when something off camera is too loud, too strange or too irritating to ignore. Because the French delivery is so expressive, even viewers who do not speak the language instantly understand the annoyed meaning.
