Bar star fag hag
The girl that goes to bars every night with her gay boy friends. She's usually wearing form fitting jeans. Not too upscale. But, competition for men's attention is fierce (bisexuals, turning men straight) and she should still flaunt her feminine figure. Although, manly-men are typically afraid of the glitter-clad posse, and she has no luck.
You see this gorgeous girl at bars surrounded by all her even more gorgeous boy friends. Being a knowledgeable bro, you warn your fellow bros to steer clear of the bar star fag hag. You won't be getting into her pants tonight.
