The transgender said what's up, then the guy said "ain't nothing up" which basically means get away from me and I don't want any trouble with you. Then the transgender keeps talking and eventually gets in the guy's face and tries to fight him. So the guy fights the transgender woman and leaves them bloody on the floor of a train. It gets pretty graphic. The transgender is actually a man, so it's not a guy fighting a girl. Remember that. This is a guy vs guy fight, but one dresses like a woman.
