The line comes from The Simpsons, the long-running animated sitcom centered on Homer Simpson and his family in Springfield. Homer's exasperated catchphrase-style outbursts have long been clipped and shared by fans, and this short reaction became a favourite on soundboards because it captures his comic panic in under two seconds. Editors reuse it for fails, reveals and overreactions, keeping it alive well beyond its original episode as a shorthand for cartoonish disbelief in short-form video.
