Nerdfighters 

A nerd who fights (against the decepticons -- also known as popular people).

One who is, instead of being made of organs and tissues and whatnot, made of awesome.

The word originated in John and Hank Green's video log projected, called vlogbrothers. While John was in an airport one day (curse those grey speckled walls), he saw a video game called Nerd Fighters.

Thus, the legacy of nerdfighting began.
Nerdfighters, we fight with our brains.
Nerdfighters, we bring the frakkin' pain.

Nerdfighter 

A nerdfighter is a person who is proud to be nerdy and intelligent, and who fights to decrease WorldSuck. Nerdfighters are not composed of cells and tissue, but instead made entirely of awesome. Nerdfighters are known to perform their Happy dances when they are joyful, and each Happy dance is unique to its respective Nerdfighter. Nerdfighters are diverse in their hobbies, which can range from writing Nerdfighter songs to playing D&D.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
