There is no single famous source for this clip, as slow fart sounds are a long-running staple of comedy sound libraries and user-made soundboards. Similar effects have been used for decades in cartoons, prank videos and internet memes to signal embarrassment, failure or disgust without any dialogue. On soundboards, short bodily noises like this one stay popular because they are instantly recognisable, easy to drop into an edit, and work across languages. Its longer, drawn-out style sets it apart from quick one-note farts.
