A piaboo is someone who wants to be a math enthusiast, and believes they truly are. The word comes from weeaboo, somebody who tries hard to be Japanese, and pi, a number most math geeks are familiar with. However, rather than obsessing over the Japanese culture like weeaboos, piaboos obsess over math.

Piaboos are generally people who have played the Nintendo DS RPG The World Ends With You and like the character of Sho Minamimoto so much they want to be like him.

Behaviours include memorizing the digits of pi up to a fairly large number, saying zetta instead of very/uber/hella/super/extremely etc., trying hard in math tests and getting disappointed when your math mark isn't an A (If you want to get into a certain college this doesn't count) and using mathematical slang in everyday conversations.

Piaboos tend to hang around school libraries and outside math classrooms.

They don't get boyfriends or girlfriends so easily, since nobody really wants to date them unless they have a math fetish and their pickup lines are usually something along the lines of 'Hey sweet digit, wanna lie tangent to me?' They also tend to go for nerds of any other kind if their fellow piaboos are unavailable.
Cathy: So I got a B for math on my report card, and I was so zetta disappointed! I yelled at Ms Jones 'YOU STUPID YOCTOGRAM' and walked out the door. That -100 zeptometre better learn!
Emma: Shut up about math already, you stupid piaboo!
