Ortholysis 

(noun): the wrapping around of a mathematical function under transformation into a higher nth-dimensional space where n > 2 and n ∈ ℤ+. This twisting occurs typically when a 2D function is integrated by rotating about the x-axis in order to find the volume of the 3rd-dimensional shape.

Ortholysis is used to describe this behaviour in various different sub-branches of integral calculus. The origin of this word is still unknown. However, this neologism was rumoured to have been coined by a Romanian scientist and mathematician. i
Student: "Would the integral of y=−ze^x about the x-axis give you some sort of pulsar-like ortholysis spirally thing?"
Teacher: "Sort of. It depends on your limits and of course the fact that your equation doesn't consider that a pulsar visualisation with that equation would be rotating about the y-axis!"
Teacher: "And also the fact that the center of mass is not represented accurately in any way and you'd need to make it asymptotic."

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.
