Place it at the end of a short prank setup, after the setup builds up, then follow it with the bruh sound for a deadpan reaction and the fart with reverb for a second payoff.
About this sound
This is a single long fart sound effect that lasts about twelve seconds, stretching one fart far beyond a quick toot. It feels silly and deliberately over the top, the kind of drawn-out noise that makes a room laugh because it just keeps going.
