A person, usually female, that only attracts douchey men. Quite like a light house brings in ships from storms.
Man, that chick is really cool but she is such a douche beacon.

Guy 1: Why does that chick stay single all of the time, she's really cool.

Guy 2: She knows that she's a douche beacon, she has completely given up on dating.
