when you hold your piss for a really long time, such as a car ride, and when you finally do piss its almost better than sex.

When you're busting for a piss, and finally get to let it go, a pissgasm is the spine-tingling wash of relief that makes you go "Oooaaaaaaaahhhhhh!!!"

When you're getting fisted, your ass is opened up good and the fister pummels your prostate so hard you start contracting with an anal Orgasm and lose control of your bladder... You literally shoot waves of piss and precum all over the place.
Make sure you put down a couple towels when you get fisted with a full bladder so your pissgasm doesn't soak the bed.

Pissgasm is when you've been holding in a piss for so long that when you finally piss, it feels like you've had an orgasm
Dude, I just had the best pissgasm ever!
How long were you holding it in for dude?!
About 3 hours bro, greatest piss i've ever had in my life!
