OPK

Orland Park Killas, although they kill nothing, they're a group of rag tag teens who vandalism and do ignorant hood rat activities in the suburb of Chicago know as Orland Park. Widely hated by most everyone, OPK believes they are "Savages" and are often found spouting nonsense talking about their "Squad". They are mostly all white, but act black and think they are ghetto

"Bro did you see OPK knock that old lady's garbage can over?"

"Be careful out in Orland Park, OPK might threaten to do something to you"
"Woah dude did you hear OPK talk back to their teachers!"
