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 1: He loves his girlfriend, but he wanted more then just pussy, so he tried having sex with a shemale to get pleasure from the anus g-spot.

Guy 2: So what does that make him?
Guy 1: Trisexual

Get the trisexual mug.
A person who can be attracted to three different genders.

This could often be the two binary genders (male and female) plus another non-binary gender such as bigender or agender. Though it could also be only one or neither of the binary genders and two or three non-binary genders.
Someone might also describe themselves as trisexual if they are attracted to males and/or females and also transgender people.

Trisexuals could also be described as being 'polysexual'. (Attracted to multiple but not all genders)
"I identify as trisexual, not bi, because I like boys and girls but I'd also date a trans person."

"She's dated both men and women and also a couple of agender people, so she identifies as trisexual."

"I used to think I was bisexual but then I stared getting crushes on another gender so I decided I was trisexual."
