When some on is making all sorts of excuses for flaking. Or when someone does you dirty, and someone else asks you what you think of them, your response should be man, FTF (Fuck That Fool)
Abbreviation of "Female to Fmale," a MTF-vectored or intersex person who considers herself transitioning from female to female, as she has always been female, though not in the way it is traditionally (incorrectly) defined.
I'm FTF, saying i'm MTF gives people the impression that I've been a man at some point in the past, and I have not.
