Verb. When one has to pee and is wearing a pair of shorts with no zipper or buttons, rather than pulling down the top of his shorts and pulling his weiner over the waist of the shorts to pee, he chooses to pull his weiner out and pee by pulling the bottom of his shorts to one side.
Joe (standing next to and watching Tom pee at a public urinal): Yo brozay, what are you doing over there? Don't you just pull your shorts down to pee?"
Tom: "No man, this is soooo much easier. I'm peeing out the bottom. Much less of a hassle."
