There is no widely documented origin for Skully Fart, and it circulates mainly as a short, user-shared clip on soundboards rather than as a line from a film or show. That is typical for brief fart noises online, which travel because they are instantly recognisable and easy to drop into almost any funny moment. Creators reuse them in memes, gaming clips and reaction edits because the sound needs no explanation, and its half-second length makes it useful for quick cuts, short videos and livestream reactions where a longer joke would slow the pace.
