look up any word, like lemonparty:
the abbreviated form of fraternity. A typical "Frat" member is composed of Neanderthal-istic features and lower then average intelligence. They suffer from inferiority complex and believe that all women are there toys (especially the gullible I.E, Sorority girls) who buy all of there garbage. Frats typically vary in number although intelligence and conscious thought degrades as the number increases. While often considered a collegial affair, frats do not excel in learning atmospheres and are intimidated by reading, writing, or thinking. IF YOU are threatened by someone of this nature call animal or pest control. As a last resort throw a book at them.

Guy 2: no, those girls are dumb as shit..
Guy 1: mmm....

Frat is a word that gives away a GDI's ignorance. It's a fraternity. Yes we party. Yes we have a good time, but being greek is more than that. It's brotherhood, it's tradition, it's morals and values instilled into us from a previous generation when manners were used and gel in hair wasn't. On my campus, the greek gpa is much higher than the non-greek gpa. So if you think we're all a bunch of guys that dress similar and drop out of school, you're completely mistaken. We dress like adults, have better grades than you, and one day we'll be your boss and you'll have to dress exactly how we do now when you work in your cubicle while we're in our corner office smoking a cigar and drinking scotch.

A clever misspelling of the word "fart", to enable the user to say it in situations that would otherwise be unacceptable.

The bodily function of passing intestinal gas (flatus) via the anus.
