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!
