Googled "insults ftm discrimination", tried looking for pejorative synonyms to "ftm" in the Urban Dictionary, checked some trans-gender LJ communities.
I want to write a fic with a trans man (ie a female-to-male transsexual person). This character is Italian and a member of a mafia family. This is manga mafia we're talking about, so they're practically teddy bears compared to the real deal, but I'm planning to write them as conservative and more or less sexist and trans-phobic - some of them paternalistic, others just plain hostile and offensive.
The character would be a young adult in the fic, and the fic will include passages of his childhood. As a young adult he's dressing like a man and binding, but he never got an operation or any medication. Even as a child he's always had a temper and been violent and aggressive.
My problem is that I don't know what derogative words or comments are typically used against male transsexuals. Neither in English nor in Italian.
And I'd like to have some input from people who have experience with it, rather than just make it up and get it all ridiculously wrong, or somehow making it turn out offensive.
So basically, I'm looking for insults, slurs, insulting or disrespectful comments or gestures aimed at a girl who acts like a boy/ a teenage girl who claims she's a guy (both things that the character's peers would say and things that adults/ his elders would say). Especially the crude and vulgar stuff.
Anything would be helpful, even if it's not specifically Italian, though of course Italian words would be awesome.
