The exact origin of this stretched what shout is unclear, but it spread as a generic reaction clip across meme pages, soundboards and short video edits. Creators use it alongside other exaggerated reaction sounds like the emotional damage meme and the oh my god meme to mark moments of pure disbelief. Its very short length made it easy to repost, remix and drop into unrelated scenes. It remains popular because the meaning is instantly understood in any language context, even without knowing who first recorded the voice.
