Perhaps the worst of all boners, this boner occurs when one really has to piss. It normally appears during what was originally an uneventful walk to class, or whilst playing a friendly game of Parcheesi with some bomb-ass broads. Only goes away after relieving oneself...

Control your fluid intake, you idiot. No one wants one of these bad boys to pop up in the middle of nowhere.

The act in which one is drinking a beer and taking a piss at the same time thus, the digestive system experiences an equilibrium between these fluids.

A pissing contest to see who can pee the farthest.

A Urinary Canal is formed when the excess belly fat convers up the sex glands, so you have to roll the skin until you make a passage(canal) to get it to the toilet.

It's like when your gut flora migrates to your urethra and infects it, making your pee smell funny.

when you're texting and peeing at the same time and you accidentally pee on your phone (males only).

ex.: What happened to your phone dude?
My phone got a urinary text infection last night at the bar. I pissed all over my shoes, too!
That's gross. Go replace your phone and burn your shoes.

When the girl is urinating while the male is standing in front receiving a blowjob. sometimes reffered to as pissing blowjobs or pb&j

1. Thats when you wake up in the morning with a RAGING hard on as a result of the need to pee. It really has nothing to do with hormones... truly a mystery to us men. We just kind of wake up sometimes and think "awwwww NUTS I wanted to stay in bed, now I got to get rid of this thing by taking a pee." Even worse is the physical manuevers one must use in order to point the erection DOWNWARD. The average fellow knows nothing of acrobatics, but I would think a mans pee hard tactics are as unique as a finger print. I myself start with a brisk walk to warm the muscles and of coarse a few squat thrusts followed by a good stretch. I then remove my garments, place myself infront of the bathroom sink and raise my arms directly up towards the sky. In one fell swoop I give it one good cartwheel to the left which places me in a hand stand precisely infront of my toilet. I then exhale slowly, and begin urinating. I have found that listening to Mozart can sort of get things flowing.

Exclamation if you are to dumb to say words.
