A guy who says he's bi but actually he prefers to finger his own butthole every night. He doesn't like men or women, just himself. He will hit on people to get them to finger his butthole and then dump them.
Bob: Who's that guy?
Jerry: Oh that's dirty Alan, don't let him hit on you because really he just wants you to finger his butthole!
