A girl who pretends to be bisexual to gain attention. She has never done more than kiss a girl, but tells everyone she is bisexual for the shock value.
Andy: "didn't you say she was bisexual?"

Matt: "She said she was, even told me some dirty stories! Then I found out she only kissed a girl one time, that broad is a Bi-Bluffer!"
