PI

PI is short for the Philippine Islands. Philippine Islands is the old name of the Republic of the Philippines. The Philippines was formerly known as Las Islas Filipinas, named after King Felipe II of Spain, when it was a colony of Spain from 1565 to 1898. Then it was Anglicized and it became known as the Philippine Islands when it became a U.S. territory shortly after the Spanish-American War of 1898. In 1946, upon independence from the U.S., it became a republic. The name of the country was then changed to the Republic of the Philippines.
Yo, I’m going back to the PI next year.

The Pi in Me

When there is a hidden element of π residing in all humans (or maybe even animals), whether they know it or not, regardless of their experience of school math—that pi-mind consciousness that intuitively seems to be guided by some Higher Being to convey new insights about the “sacred number” to humanity or any living entity.
When someone puts themselves in a Zen-like or transcendental state, the chances of them experiencing “The pi in me” aha! are higher than when they’re constantly being bombarded with a deluge of sensory input.

Pi Pa

A creepy ass grandpa, the type of grandpa that doesn't care about incest and talks like a smoker. Gets mad about everything and is horny all the fucking time.
"MOM!! Pi Pa is having the cat lick milk off his dick again!!!"

Predictive Pi

When both mathematicians and AI could forecast new mathematical results on the number π based on published papers and from recently awarded pi-related research grants.
Predictive pi has somewhat democrarized previously secretive research conducted by both pure and applied mathematicians around the globe.

A Pi-Free Math Book

The mathematical equivalent of a meeting-free day or passport-less travel. When the sight of the symbol π is enough to trigger panic or paranoia among billions of folks worldwide, who think they weren’t born or blessed with the “math gene.”
Just as a math book without equations or formulas could raise the sales figures by a few folds, a pi-free math book could give thousands of math-anxious folks more confidence in picking up a pop math book without feeling unduly stressed.

beta theta pi

The best frat ever. Which isn't saying much. All the guys are mid, yet the atmosphere is top tier. If you go to a beta party, you will feel like a ten simply because these men are desperate. Stay away from Topher.
1: Did you hear beta theta pi is throwing tonight?
2: Oh shit! Don't drink that wine again!
