There is no single famous movie or viral video behind this clip; it belongs to the loose family of gross-out meme sounds that circulate on soundboards and in short-form edits. Its appeal is purely in its length and exaggeration, which makes it closer to a long brain fart joke than a realistic effect. Like a fart with reverb, it is shared mainly as a reaction sound, dropped into prank videos, gaming fails and Discord jokes whenever creators want an instantly recognisable, childish punchline that needs no setup or explanation.
