Nobody has pinned down a single source for this clip, so its history is really the history of how soundboards work: a short, funny one-word reaction gets uploaded under a jokey filename and spreads because it is instantly usable. The quirky spelling in its original title suggests it circulated through meme soundboard communities as a reaction audio rather than as a quote from a show or film. At under two seconds long, it fits the exact slot creators need for a quick hush punchline, which is why it keeps getting played, shared and downloaded as a tiny instant-meme.
