Young college female, often times a member of a sorority, who spends an excessive amount of time having sex with brothers of a fraternity.
the term derives from fraternity + mattress, because the slut spends so much time under brothers that she might as well be their bed.
"Bro, you see that frattress over there? Yeah, the one on top of the table. I'm gonna do work and put her to use tonight."
"So, I was banging this frattress the other night, and after we got done she told me not to tell any of my brothers. You know she's just gonna tell those other sorostitutes how awful of a guy I am."
A definition of a female who exhibits gay tendencies. One who choose not to do things for any reason. Doesn't pick up your phone calls. Drinks out of a straw puckering her lips.
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.
