A person, usually a girl, who either claims she is or very obviously plays up being bisexual to get attention from members of the opposite sex, or to try and get in with the cool crowd.
Look at Emma making out with that girl. She's blatantly just attention bi - if a real lesbian ever came up to her she'd run a mile.
