look up any word, like no soap...radio:
Any absurd hat worn by a fraternity brother. Must be worn backwards. Must be adjustable, as fitted hats are far too expensive. Generally a bright or neon color. Often times can feature sports teams, or outrageous companys. However, if a Polo hat is found, it is most assurdly the definition of a Frat Hat.
Did you see Brady's Bills hat? The definition of a Frat Hat.

Beef, your Frat Hat is amazingly clutch because of the Polo Logo.

D-Brown always has his Frat Hat turned backwards.
