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.

I have read in many and varied sources that "schoolboy" is street-talk for codeine. Now, somewhere or sometime perhaps it is or was, but not ONCE, as in never, during my reasonably extensive research regarding various street scenes did I ever hear it used. T3s, T4s, codeine...yeah, those one might hear...but schoolboy? Me not think so, unless it is just something pre-1960s and fell out of use.
