This sound is mainly used online as a short reaction clip for edits, pranks and roast-style videos rather than for a widely documented film or TV source. Its appeal comes from being instantly understandable: one word, one joke, one beat. Creators keep using it because it fits short-form comedy well, especially when paired with a freeze frame or a heavy hit like an instagram thud. It also sits in the same family of blunt reaction audio as a shocked sound, where timing matters more than context.
