Dude, you guys have just ran with "ballsack". I started that phrase and it has apparently been shortened from "my ball sack". I have used it in accordance with most other examples here: however, I have a modifier- ping! The word "ping" is used to show you agree with the ballsack sayer.
you: Man, that guy's gonna take one in the frank & beans if he don't stop pokin' that donkey with that pointy stick.
dissinterested listener: My ballsack.
