There is no single famous source for this clip, which is typical of short prank sounds shared on user-made soundboards. It appears to be a simple designed effect that combines footsteps with a fart, made to be reused in jokes rather than taken from a film or television show. Because the idea is instantly understood without dialogue, it travels well in short videos, reaction clips and gaming moments, where a walking character suddenly becomes the punchline. Its appeal is broad, low-effort comedy that works in almost any language.
