When a male has not had sex, jerked off, or had wet dreams for a while and the balls droop due to excessive semen back up.
Jack: I'm so frustrated!
Friend: Why dude?
Jack: My girl ain't giving up the pussy!
Friend: Man u must have dogballs
Jack: The shit is hitting the ground!

Dogballs
The act of lowering your nut sack on to the lips of someone that is passed out. The nut sack touches the lips but does not actually enter the mouth as it does in the act of tea-bagging.
Did you see what Jerry did to his buddy the other night at the end of that party? He just dropped his nutsright on his face - dogballs: the ultimate degradation.
