Little Person Syndrome(L.P.S.)

Syndrome caused by an inferiority complex usually directed at stature or height. In women this may cause a variety of problems from "Bitchy-ness" to the urge to stand on large objects in order to feel some sense of "dominance" over others. Calling a woman who suffers from L.P.S. "tall" is a big compliment and will make them feel good about themselves. In men the problems multiply; men, already having an aggregation of complex's pertaining to their own inferiorities, become arrogant little fucks, who buy big trucks, and treat people like shit.

This syndrome is similar to L.M.S. or Little Man Syndrome, which is an inferiority with the size of ones own Male reproductive organ.
"Man that girl suffers from L.P.S. real bad she's just being a bitch to everyone."

"E.H.(hahah) is trippin', must be the L.P.S."

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.
