Frat Tat 

A Frat Tat is when you put roofies and a young lady's drink, have sex with her and before she awakens from her roofie induced slumber, draw all over her face with a magic marker.

I'm not sure if I had a good time but I did wake up with a frat tat so how bad could it have been?

frat matter 

The miscellaneous unknown substances that you find inside frat houses. Said substances are often composed of beer, vomit, blood, food, piss, and anything else mixed together. Often found on the walls, the floor, under the stairs, or really anywhere imaginable.

During morning cleaning up

Pledge1: What's the fuck is smeared on the wall?
Pledge2: Frat matter...

Frat ass 

A dumbass who thinks it's okay to do drugs, get STDs, and shoot (literally or metaphorically) other people in the face. He doesn't nesscessarily have to be in a fraternity, he just has to show stereotypical frat boy douche bag qualities.

21 Jump Street is funny and all, but let's face it. It's basically a frat ass' wet dream.
