osbourn

This is the short form of Osbourn High School in Manassas, VA. For the most part, it's a fairly boring place. Unfortunately, the school is of the shittiest quality and the adminstration is corrupt to the harsh detriment of the students. With many stupid and senile teachers, it's a wonder any students manage to be accepted into college at all. It's a shame so many tax payers pay for their children to be cheated out of an education.

-"Hey do you like your high school?"
-"Nah man, I go to Osbourn."
