pi boyz

The best fucking band ever created, they assemble each 1000 years to fight against evil. Born from the pits of Mordor Prezi and his friends shall free us from slavery once again. Some say they are related to Piratas de Villa Helena.

Person 1: Dude, the new song that Pi Boyz released is totally sick.
Person 2: Sure dude... *suffers a seizure*

Person1: lol

Law of pi

In engineering, every task will take exactly 3.141592 times as long as initially anticipated. The Law of pi is therefore commonly used along project managers when they ask engineers how much time they think they need to finish their work.

Arjan: How long will it take you to finish the design of those tubes?
Vincent: about one and a half hour I think
Arjan: OK, so taking the Law of pi into account, that's gonna take you exactly 282 minutes

Pi Clock

A normal clock in which the numerals representing the numbers 1 to 12 have been replaced by only three irrational numbers, positioned at π, 2π, and 3π.

What is the acute angle measure when the minute hand of a pi clock points exactly at 2π while the hour hand has moved past 3π—or when the time is slightly past 9:30? Answer: 97.3°.

The Man Who Mistook Pi for Pie

When on hearing the sound of the number π, an autistic person or idiot savant thinks of a slice of a cake or pizza instead, or equates either word for something else that is unmistakably alien or paranormal.

Just as the man who mixed up his job for his life, Prof. Paulos, who mildly suffers from schizophrenia, occasionally sounds like the man who mistook pi for pie.

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!

pied noir

Sometimes used as a term for any European born in Africa, but directly used for ethnic French born in North African colonies before their independence (1830-1960).

Mainland French do not have a good relationship with pieds noirs (plural version of pied noir)
