The Butt Nut Fart is an action preformed by 3 people. One must be the butt slapper, another is to be the nut puncher, and the last is to be the one getting hit. The 2 hitter must hit the person at the same time which in turn will cause a fart.
Tom: Hey, what are you guys doing?
Chris: You’ll see Jeremy and Chris: BUTT NUTFART *Smack* *punch*
Tom: *Farts*
