"Anything higher than a 93 is inefficient."

Applies to the grading system where a 93% is for the purposes of GPA the equivalent of a 100%. Any grade higher than a 93% earns the same 'A' as a 93%, so the work done in getting, for example, a 95% was unnecessary. Traditionally used by students when they have a good grade and do not feel like doing their homework.

Coined at Madison-Grant High School at the end of the year 2012 by a student after days of meditation.
Michael's Mom: Have you finished your Spanish homework yet?
Michael: No
Michael's Mom: Then what makes you think you should be playing video games on a school night?
Michael: The 93 Rule. I have a 97% and there aren't enough points in the rest of the semester for me to not get an A.
Michael's Mom: I see. Carry on.

He used the fact (before some updates) that if you hit a chicken with a shovel, you were given the loot 1 or 2 feathers and a piece of chicken, wich can be consumed.
person 1: Oh, look! A chicken!

Person 2:I envoke Rule 93! *hits it with shovel*

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.
