Pee-rect
(Adj) When you have a boner in the morning but have to pee so badly that you can't actually have sex or jerk off. You have to wait for your woody to go down just to pee. (Unfortunately, by that time, you may have lost your chance.)
I'd totally bang you right now, but I'm too pee-rect. Could you cover up or something? I gotta get this pee-rection down first so I can pee.
