ball boil 

When the shower isn't working and you have to dip your balls in warm water to wash them!

Hey man, I call dibs on the first ball boil in the morning!!

No man, the early ball catches the first boil

Did you have a ball boil this morning, there's an awful stink out of this cup!

attaching metal plates around your balls to apply pressure to them on a hot summers day, only to explode inside

i now truly cannot have kids, since using the ball boilers!
