A dirty prank where someone poops in the water tank of a commode, leaving a rank smell and bits of poop showing up in the water everytime you flush.

A sexual situation where the male is going to town own a girl. Just before blowing his load he sticks his fingers in her ass and smears the contents on his balls. He then shoots his load onto her face to make a nice line and then teabags her. His balls will either go left or right and thus the foul ball.
