Urban Pi

Irreverent or politically incorrect math definitions on and about the number π, most of which stand zero chance of ever being published in a school textbook, because they are deemed inappropriate or unsuitable to the immature or puritan mind, or to those with a poor sense of humor.
How could pi enthusiasts be deprived of a lexicon of urban pi terms or phrases just because some of them are allegedly blasphemous or irreligious or preposterous?

Reel Pi

When movies on math, or those that depict the odd behaviours of oft-mad mathematicians or idiot-savants, never fail to mention the number π and some of its magical properties.
With pi being part of pop culture, it’s not surprising to hear mathophobic actors in Hollywood complain about reel pi, as it reminds them of their bad experiences of school math, especially if they’d flunked the subject several times prior to making it big in the entertainment industry.

Twitter Pi

Composing a short story (factoid, haiku, joke, …), or posing a math problem, using 140 (or 280) characters or less on or about the number π.
Three examples of Twitter Pi are:

a) A haiku entitled “Pi in the Sky” goes like this:
Pi is three only.
For the Bible tells me so!
I shalt not doubt it.

b) Trump promised MAGA evangelicals in red-pilled states: “If re-elected, I’d decree π to be 3 for all true-blue patriots.”

c) A math toughie: If 1! = 1 and 2! = 2, show that (1/2)! = 1/2 √π and (–1/2)! = √π.

Pi-bond

A dance move which involves pointing your elbows out and rotating your hands around by your chest as if imitating the movement of the bond between 2 p-orbitals as seen in chemistry.
Everyone thought he had lost the dance-off until he pulled out the Pi-bond move.

Pi Second

The fifty-third second of 9:26 a.m. of March 14, 2015. So called because 3.141592653 is pi down to nine decimal places, and Pi Second is 3/14/15 9:26:53.
On Pi Second, we will play the sound of a bell ringing for all the world to hear! Pi Second is only one second out of every 100 years, so it only happens every three billion or so seconds. Enjoy the second while you can!
