What is Fart Tweaking?
1.
A move performed by moving your anus cheeks during a fart to effect its sound.
This can only be done on farts longer than six seconds and usually involves changing the pitch or vibrations of the fart.
Pfffffttttttttt-Paaaaaaaangggggggg
Dude, did you hear how great my fart tweaking was there? It started out all soft and then I tweaked it to get some nice bass and great volume.
