That amazing feeling you experience after you have had to pee for an incredibly long time, and you finally get to the bathroom. The euphoria lasts for a solid three hours or so, depending on how long you've had to pee.
Girl 1: Damnit sam I really need to pee.
Girl 2: Too bad the nearest bathroom is an hour away!
(one hour later)
Girl 1: OH MY GOODNESS I'M EUPHORIC!
Girl 2: Are you experiencing post-piss bliss?
Girl 1: You bet your tits I am!
