clapper

A loud, sometimes painful, fart that feels and sounds as though the anus and asscheeks are rapidly opening and closing with considerable force.

"Whoo, that was a serious clapper."

float one

To fart, as with an air biscuit.

Person one: "What the fuck is that fucking smell?"
Person two: "Sorry dude, I totally had to float one..."

Optional: "I totally floated one..."
