THAT KID in grade/high school that never did anything wrong in fear of the repercussions, i.e. bad grades, people thinking less of him, or getting yelled at by mommy. usually a tall lanky kid that goes to college and becomes a pothead!
why do you study so much lapo, your such a SCHOOL BOY!!!
A way of pissing urinating against a wall during a drunken state whilst pulling your keckstrousers (including undiesunderpants) down to your ankles and lifting up your shirt. This is known as a schoolboy as it replicates the way little children piss in urinals in public toilets and the way we all pissed as a school boy. A true schoolboy will involve pissing no handed whilst holding up your shirt with both hands.
