to hump a girl's leg, jizz in your pants, lick her face, and then proceed to leave the premises...SAM
a dude who pops the cork before the champagne is chilled
a male plagued with the embarrassing defect of shooting off his gun before the order to fire is given
Guy 1: Did you hear about Sam last night?
Guy 2: You mean the Teri thing?
Guy 1: Yeah, that guy's a jizz fizzler
Guy 2: I know. He blew his load in his pants before she even had her top off.
When a guy getting a blow job puts on a Darth Vader mask and ruins the moment for the chick giving him head just before he blows his load. Also, he breathes into the mask telling her he's about to blow his load while sounding like James Earl Jones with the heavy breathing bit.
"I was giving Matt a special yeaterday and he decided to pull a Darth Vader on me."
