Delta Sigma Pi

Delta Sigma Pi is a so-called professional organization that allows underage drinking at official events and only becomes upset when the pictures are posted on a website.

The underage drinking took place at a Delta Sigma Pi Spring 2007 Pledge Social Event known as the Heaven and Hell Party. Their idea of community service is stuffing three trinkets in a paper bag and handing it out to parents whose children are in the hospital. If a member should try to voluntarily withdraw due to grieving over a family death, the executive committee just might suggest that the grieving person seemed to be fine during the pledge process and therefore should not be allowed to withdraw. Give this all of the hissing and booing that you please, but I have seen this with my own eyes.

Sigma Pi

A raging cesspool of homosexuality, frequent nudity, and prison shower gang-bangs. Contrary to popular belief, most of the brothers are actually bisexual, and enjoy the company of a lady as well as man. The house is an odd mix of classic "bros," completely worthless potheads, everyday regular normal guys, just plain weirdos, and every possible combination of the above. It is balls deep in Urbana in order to segregate Sigma Pi and maintain the purity of the rest of the Greek Community.

"Hey you worthless pothead, stop smoking pot in the house!"
"Ill stop smoking pot when that weirdo puts clothes on!"
"Ill put clothes on when Kates stops acting like an everyday regular normal guy!"
"I'll start having a personality when all the bros close their doors when getting a blowjob!"
"Zook says I agree with all of the above in Sigma Pi."

Holy Pi

When the number π self-proclaims to be God’s “anointed” number, because it is the most famous constant in the whole of mathematics—no number has had such an impact on popular culture that even some mathophobic folks wouldn’t mind tattooing it conspicuously to look mathematically cool in the same way that unbelievers wear a cross to appear religious.

Because π is the beloved symbol of choice for millions of people worldwide, or even deified by some pi fanatics and numerologists, it’s not preposterous for the “sacred number” to be conferred the title of “Holy Pi.”

A Ho Pi

A negative play on the name of the sorority AOPi (alpha omicron pi). This "nick name" implies that AOPi's sleep around.

Student: Look at Beth, she's so hot!
Frat boy: well you have a shot, she's an A Ho Pi.

Grow the Pi

When you give the value of the number π correct to more significant figures or decimal places in order that a better pi approximation could be used in a calculation.

Rocket scientists want to grow the pi to play safe, because working with more digits would help reduce any loss in human lives.

The Pi Self

When the number π is suffering from imposter syndrome in spite of its perceived or recognized beauty, ubiquity, and utility in many areas of mathematics and science.

Since the start of the pandemic, there have been few new theorems or breakthroughs on the irrational number π, so mathematicians have started to hypothesize whether the pi self phenomenon isn’t finally being manifested.
