Yellow Sack

Having a pimple so large on your ball sack that it appears to be a third yellow ball. The surface tension is so tight that very little pressure creates a yellow eruption of ball puss.

Sack Clack

The act of being completely naked while thrusting so hard that your balls sack starts smacking against your taint hard enough to make a clapping sound. It is quite and impressive party trick might I add.

Yesterday, my mom caught me doing the sack clack and she started to join in and she was really good at it!
