M.S. 216

This is a wack ass school where a vault cunt named Mr Rodriguez follows your ass and gives detention on the daily. This school is full of kids who wanna be all gang. They got the brick shoes and try the most for kids to praise them.

The Definition of M.S. 216 is

Friend “ where’s the last place you don’t wanna go”
Me “ Ms 216”
Friend “why”
Me “ last time I was there I got suspended for taking of my mask”

m.f.

aka mold farm. A perfect place to hide rotten ravioli and popcorn kernels as well as any other random shit you may encounter in your fridge. this may include milk, pancakes, vinegar, bread, eggs, and CLAUSSEN pickles. beware of maggots and older, slightly more mature people finding it in a cabinet in your basement.

The kids parents were f-ing pissed when they found that bad-ass m.f. in the cellar because it smelled like corn chunkidge.

M.P.M.S

PMS for boys. It is merely phenominon addressing the issues that boys have in general. When they are moody, mean and think they are too cool yet, they only hang out with themselves

Harison wants to hang out with himself again, he must have M.P.M.S
