That seems shitty (also FYI trap is a nasty word). I’m not doing that at all. I try and be very clear that I’m a girl. A masculine girl who likes sports, cars, and getting dirty but a girl no less.

It means AMAB. Best way to remember is that trans terminology describes identities we identify with, or direction of transition. So trans women are women, and transfem (transfeminine) means feminine or feminizing.
