Mathematress 

The in-bed mathematics that one performs in order to calculate how many hours or minutes they will be able to sleep for if they fall asleep immediately. Usually this is done in desperation after failing multiple attempts at falling asleep. The calculations usually begin while uncomfortably lying awake and trying to force yourself to sleep, you use the time you intend to sleep by and the time you have to get up, and all time in between is the Mathematress calculated sleep time.
*Guy looks over at the clock* "Shit it's already 3 and I have to be up at 8...well Mathematress says I'll only get 5 hours if I can get to sleep right now.....right now......damn!

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.
