This clip has no single famous source, which is typical of short bodily-humor sounds shared on soundboards and in meme edits. Rather than coming from a well-known film or show, it circulates because it is instantly recognisable as a burp and instantly usable as a joke. Creators reuse it in prank videos, reaction edits and short-form comedy, where a fraction of a second is enough to sell disgust or silliness. Its staying power comes from that simplicity: it needs no context, works across languages, and fits the fast, crude humour of online memes.
