This louder cut appears to be a user-uploaded variant of a generic cartoon fart effect, rather than a line from a film, show or named character, and no single original source is widely documented for it. On soundboards it sits alongside other short prank noises, where visitors reuse the same few seconds again and again because the joke needs no setup. Its staying power comes from that simplicity: a familiar, instantly recognisable rude noise that works in any language and fits the short, punchy rhythm of memes and reaction clips.
