pi-gu

Variation of Mandarin Chinese, roughly translating as "rectum", "bunghole" or "asshole" (but not a person who's an asshole.)
"You think you're better than other people!"
"Only the ones I'm better than. And now I'm thinkin' that's the very thing you're placing value on today."
"I place value on the fact that the stick up your pi-gu is about as big as the one Harrow's got."

Alabama pi

The number 3.

Using the number 3 instead of the real value for pi because you are no better at math than the average redneck.

A hoax news article posted on the Internet saying that Alabama was changing the value of pi to 3. Many people believed that Alabama would actually do this.
I just did some real quick calculations in my head using Alabama pi.

Pi Persecution

When the number π is being spied 24/7/365 online and trolled by envious or jealous numerical constants, who couldn’t stand her global appeal or fame, as thousands of mathematicians and math educators worldwide maniacally devote an obscene number of hours every year trying to discover hidden properties about her.
Constants like e and 𝛷, conspiring with √2 and i, have been repeatedly accused of pi persecution, because they’ve allegedly or unprovenly ganged up to serially and spitefully downvote any old and new Urban Dictionary entries on π every day.
