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!
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.
Dude, I just scored a scrip for T4s 'cause I told the doc my BACK hurt!
(One would NEVER say that one just scored some "school boy.")
The narcotic drug Codiene. Usually availible as a hydrochloride salt.
When I was a school boy, we used to drink cough syrup 'cuz it had school boy in it back then. Now it's got that dextro shit in it. That shit'll mess you up!
