A "Trans Groupie" is a person who thinks they are transexual or transgender but isn't. Someone who says they are changing genders when they have yet to strap-down their breasts, wear fake penises, inject estrogen/testosterone, or go through any sex changing operations at all.

A person who one day, after for their whole lives being male-bodied or female-bodied, wakes up one morning and decides that everyone now needs to call them by opposite gender, or neutral gender pronouns, and then gets offended if people still continue to use the actual "correct" pronouns to describe that person.
All those little, annoying, boyish-looking lesbians are trans-groupies.
