A derogatory name for a Fraternity. Often used by Gel-headed, Abercrombie wearing, spray-tanned douchebags. Often used in the north, or anywhere outside of the South East (Virginia, North Carolina, South Carolina, Tennessee, Alabama, Georgia, Kentucky, Louisiana, Mississippi, Texas, and Arkansas), though they may just be too stupid to understand that it is derogatory.
"Frats" usually consist of the previously mentioned Abercrombie, gel-head, spray tan doucherockets. They tend to give real fraternities a bad name.
I'm not in a frat. It's called a fraternity, fucking "Jersey Bro"....go take some fucking steroids, Guido.
