pi day

the one and only day that you might actually look forward to going to a math class, as many teachers allow their students to bring in a pie on this special occasion. unless of coarse your math teacher is a fucking nazi, in that case they might just spend the whole period ranting about how cool some retarded number that goes on forever is. yes thats right 3.14 is not technically pi, it goes on and on and on much like ancient old men who think shit like that is cool.

kid 1: "hey man wanna skip next period and smoke a j?"
kid 2: "Yeah... wait today is pi day! we cant skip math class today! we need to smoke now so we can take care of our munchies in there dude."
kid 1: "totally"

Pi Delta Psi

Pi Delta Psi (ΠΔΨ) is an Asian-American Cultural Interest Fraternity founded at Binghamton University on February 20, 1994. The mission of Pi Delta Psi is to break down cultural barriers by fostering individual growth in the areas of "Academic Achievement, Cultural Awareness, Righteousness, Friendship and Loyalty"
Pi Delta Psi is a brotherhood. A brotherhood that commit to the community and volunteers. A brotherhood that raise cultural awareness in the community. A brotherhood that is a life time bond.

P.S What is with all this hate stuff? I thought other Asian Fraternity promote Asian awareness not hate on them.

Friend 1: Oh wow, When did this park get cleaned up?
Friend 2: I saw a bunch of Pi Delta Psi brothers at 7 in the morning cleaning it.
Friend 1: Oh man, they sure do a lot community service.

Pi Beta Phi

a group of women who are smart, loyal, hardworking, trustworthy, classy, absolutely beautiful, and always looking for a good time; basically a combination of every aspect a guy would want to marry and every girl would like to be.
When you meet a Pi Phi, you realize immediately that there's something unique about her. There's an unmatched level of integrity and commitment to excellence, and a general aura of potential that sets this person apart from the pack. That's because she's a Pi Phi through and through and a member of a premier organization for women.

I want to be a part of Pi Beta Phi, an excellent organization
