This clip has no single famous source, and it circulates as a generic user-generated soundboard effect rather than a line from a film or show. Its appeal comes from combining two familiar rude noises, the raspberry and the fart, into one short burst that works without any context or dialogue. That simplicity helped it spread through meme edits, reaction videos and prank compilations, where a two-second gross-out can replace a spoken insult. Because the joke is visual and immediate, it keeps getting reused whenever creators want a cheap, silly shock.
