Put this clip at the end of a prank setup, after the victim reacts, then follow it with the Vine Boom Sound Button for a heavy punchline. For a bigger prank sequence, start with the Classic Fart Sound Button and let this one close the bit.
About this sound
This is a single drawn-out fart sound lasting about 2.6 seconds, with a low, rumbling tone that stretches on longer than a quick burst. It feels crude, silly and deliberately over the top, the kind of noise that makes a room groan and laugh at the same time. It works best as a gross-out gag rather than a subtle background effect.
