A person who is interested in having sex not only with an opposite sex but also with same or anything. Trisexual is basically a person who will do anything to get pleasure, be it have sex with a girl, or have sex with a rubber doll. 95% of the time when a trisexual has sex with same gender, he does not have any kind of romantic feelings for him, just purely sexual desire for pleasure and nothing more.

Guy 2: So what does that make him?
