The euphoric shiver felt by the human male during a long-awaited urination.
I had such a violent peegasm I pissed all over the leg of the guy next to me, and he subsequently proceeded to beat the shit out of me. But wow, what a peegasm.
The intense pelasurable feeling u get when you let your pee out after having to go bathroom very badly.
(Runing to the bathroom after drinking a gallon of water two hours ago) " AHAHAHAH it hurts so bad where is the bathroom. YES THeir IS THE bathroom!!!!( ziping pants down and piss coming out) AWwwwwwwwwwwwwww" (your friend)" damn he just had peegasm!
