This clip is mainly known online as an anime reaction sound rather than for a clearly documented single source. It spread through meme edits, short-form videos and gaming compilations where creators needed a fast disbelief cue with a stylized anime feel. Its staying power comes from how compact and readable it is: viewers understand the joke immediately. It fills a similar reaction role to clips like nope, but with a more exaggerated, internet-native tone that fits edits, caption jokes and sudden punchline reveals.
