What happens when a bunch of horny males (most often adolescents but some adults are pretty depraved as well) have a circle jerk (everyone masturbates in a circle). The only difference between this and a circle jerk is that marks are awarded and a prize is given out at the end. Points may be awarded based on distance, volume, odor, endurance, or "oh" face. Prizes may include, but are not limited to, being permitted to have sex with one of the other guy's sisters.
I'm saving it up for the big jizz off this weekend. Pete's sister is so hot and I think I'm going to win

A loser that always fucks things up.
One who is also known as a perpetual masterbator.

similar to fuck off, but can be said in public places or around a younger audience. Also, must be done with a jacking off hand motion followed by a throwing motion, as if to throw the cum at the person you're telling to jizz off
-Your ass looks fat

-Jizz off, asshole
