1. When a person identifies themselves as trinsgender, this means they think there are 3 or more genders and that they are all of them. For example, someone could identify themselves as male, transgender, gay. That would make the person trinsgender.
2. When someone is uncertain about their sexuality.
Guy 1: Yo, I heard my bro is trinsgender.
Guy 2: He thinks there's 3 genders?
Guy 1: Yeah, he's stupid.
A derogatory word used against some trans people because the person using said word doesn't accept the trans person's identity (because, of course, they know ALL ABOUT someone else's gender identity). Used out of a failure to understand that gender is a social construct, and you can identify as any gender.
Also used against fake troll blogs on tumblr (that identify as fairies, moons, trees, etc.) by people who are so busy trying to make a point to trans people that they don't get realise they're being trolled.
Urgh, those stupid transtrenders are only pretending to be trans! I don't know them at all, but I know that they aren't really trans!
When a person(usually a man) decides that they want to have a sex change and with that was to seek as much attention as possible. This includes starting off with a little rumor that creeps itself around and later achieving the status of preaching their sexuality. They soon become a hero and a role model due to a very ignorant 2015 American Liberal Culture.
Susan: "Did you hear Dwight went full transjenner the other day?"
Tom: "Yeah he was handing out flyers exclaiming his change, he then signed up for a few speeches to give out to some selected left side colleges, and then proceeded to take his own life."
Susan: "You're joking on the last part."
Dwight: "Who cares?"
