A lesbian that looks and behaves like a frat boy. Typical activities include binge drinking, beer pong, playing hockey and/or football, and hitting on Abercrombie-sporting femmes at queer dance parties. She can be identified by her asymmetrical haircut, plaid shirt, skinny jeans, and confident swagger. The frat dyke is cousin to the slightly hipper bike dyke, and is not to be confused with her femme counterpart, the sorority lesbian.
Laura: Gosh, I sure am excited that Beebo invited me over to do jello shooters before the Weezer concert. Maybe she'll give me her pin.

Jack: You're a lucky duck! Beebo's the finest frat dyke on the rugby team. Just check out those powerhouse thighs.
