Delta Sigma Pi

a weak and pathetic co-ed business fraternity that pretends to be professional but is actually made up of a bunch of pussies.
Gets the shit beat out of them on a routine basis by the obviously superior Alpha Kappa Psi.

DSP = Dick Sucking Pussies
"That kid is out back throwing up after a beer and a half. He must be in Delta Sigma Pi."

sigma omicron pi

A West Coast Asian interest sorority. Also commonly referred to as, "S-O-Pis". Many of the campuses that sport chapters of SOPi also have a chapter of KDPhi, Alpha Kappa Delta Phi.

"KDPhi, spread your thighs.
SOPis, look like guys." (Sigma Omicron Pi)

8-pi

A person who shares his annoying life to the world and constantly harasses the innocent with epidsodes of his/her pathetic excuse for a life.

Wow Chris, you're such an 8-pi. Nobody cares about how you got that math problem wrong. Stop following me, I don't care.

going pi

A geeky way that maths nerds express doing a 180 degree turn. (180 degrees is pi in radians)

geek: oh dear we just passed my favourite book shop (turns around)
nerd: looks like your going pi

Alpha Delta Pi

The first sorority ever formed. Their mascot is the lion and their symbol is a diamond. As with any sorority it depends on the specific chapter but in general ADPi is usually characterized with stuck up and selfish girls. They are often referred to as "Shady Pis" and when recruiting look for girls who come from wealthy families. The sorority is often split evenly between the "bookworms" and the girls who party too hard/sleep around. When taking photographs together 9 times out of ten they will be making a diamond shape with their fingers. From the outside in they may seem closely knit and sweet but "adelphae" has become very weak. This used to be a classy sorority but is going downhill along with its reputation.

Jesse: Hey man, so I went out with a sorority girl last night..
William: No wonder you have such a big smile on your face, my man got some last night!!
Jesse: Yea i did.. but now she's gone psycho because apparently she has a boyfriend and he just found out she's been sleeping around
William: Gross man. I bet it was a Alpha Delta Pi, you better get checked out!

Sigma Pi

Sigma Pi, the boys in this fraternity are only in it to associate with Greek Life, they are in no way better than or try to be better than the typical tool on campuses. Chapters consist of all the boys rejected from other fraternities and for that reason, they rely on tool shed workshops to make themselves seem like they are more than they actually are. They are better than SAE and TKE however, they do happen to look at a rush before saying "We Like Dick!"

"We're all failures; Join us at Sigma Pi!"

Hypnotic Pi

When autistic folks and idiot savants claim that hours-long meditation on the seemingly random or sacred digits of the number π puts them in some kind of trance, which allows their mind’s eye to see sexy numerical patterns or relationships, or to visualize kaleidoscopic geometric shapes in higher dimensions.

Number theorists obsessed with the properties of π love to indulge themselves in hypnotic pi activities, hoping to experience a few aha! moments, which could help them secure early tenure thanks to some breakthrough results or elegant proofs on pi that grace the pages of reputable math journals.
