The phrase itself is long established French slang, well known in everyday speech long before it became a shareable audio clip, and this short recording has no widely agreed single source or performer. Online it spread as a reaction sound on French speaking forums, messaging apps and meme pages, where users drop it in as a voice note style answer. Its appeal is speed and clarity, one second is enough to reject a topic completely, so it keeps circulating in chats, edits and soundboards as shorthand for total indifference.
