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!

Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.

Me: Woah! TLDU!
