Place it after the punchline setup in a reaction edit, then follow it with a Fart With Reverb for a second beat before a Bruh Sound Effect closes the moment.
About this sound
A quick comic fart noise slowed to 0.125x becomes almost thirteen seconds of deep, wobbling, low-frequency rumble, with every buzz and wobble stretched far beyond a normal blip. The effect feels deliberately ridiculous and awkwardly drawn out, like a thought stalling in slow motion. It lands as pure comic timing, turning a failed idea into a joke that gets funnier the longer it drags on.
