Place it at the very end of a short edit as the final beat, after a reaction line. Follow an oh brother this guy stinks moment with this tap, or precede a ba dum tss hit when you want the gag to close on a rimshot instead.
Über diesen Sound
A pitched fart sound effect lasting just 0.2 seconds, it is a tiny, high, squeaky toot sped up beyond a normal fart. It feels instantly funny and a little awkward, turning an embarrassing noise into a cartoonish punch that lands before anyone can react or take the moment seriously again at all.
