Perkiomen Valley High School 

A high school in Collegeville, PA, that is not only “home of the Vikings” but also to some of the most cliquey friend groups in the area.

The underclassmen at the school never fail to have the best bangers and the seniors make it clear to the other classes that they’re the best. Half of the guys at PV are normal but have hoe girlfriends and the other half are rap-listening junkies who look like they climbed out of sewers. The bathrooms of the school are full of juuling students and the administration usually fails to stop them. Football is the only sport glorified by the district and every sports team at PV is a cult itself, especially the lax team. However, as it has the best student section in Southeast Pennsylvania, Perkiomen Valley’s sports games are always full of the most supportive and rowdy fans.

Because of the school’s well known rivalry against Spring-Ford High School, “rams are yams” is a common saying among PV students.

Guy one: “That kid seems cool. Where’s he from?”
Guy two: “Perkiomen Valley High School”.

Perkiomen School 

Not a school. Just a daycare for rich kids.

“Why is Perkiomen school tuition higher than Phillips Exeter?”

Perkout 

An Intense ass-kicking workout that is done after ingesting the painkiller, Percocet. You are able to run faster,jump higher and dig deeper do to the fact that you are numb to the pains associated with pushing your body out of its comfort zone. You will feel superhuman. You will accomplish greatness. The next day will suck. Everything will hurt.

Craig: I want to do a workout, but i do not think i am physically capable of performing to my best potential tonight, I feel like a vagina.
Danielle: Of course you do, Lets perkout.
