Uringasm

The tingling sensation you get at the tip of the anus when peeing after holding it in for a long time, almost feeling like you ejaculated without fornicating.
Dude 1: Dude pull over, I have to pee.

Dude 2: Didn't you go before we left? Check in the back of the van to see if there's a bottle for you to pee in.

Dude 1: Nawh can't find it...ugh...I have to...go...NOWWWW!!!! UWWWWAAAAAHHHH!!!!!

*pees from the back seat all the way to the front seat windshield*

Dude 2: Dude WTF?! how did you do that?

Dude 1: I just had a uringasm and it felt great!

Dude 2: That was awesome, I'm really pissed off that you did that but still impressed!
