A term that is mostly used by Transmeds & Truescums, which means a non-dysphoric woman larping as nonbinary.
The term is a
combination of the pronoun they and the term AFAB, and is commonly used to
make fun of & mock women who identify as NB without changing their female
appearance, and call out anyone who doesn't use their pronouns.
A: Mary told me she wants to be called Moi, and goes now by they/them.
B: But she is still
presenting female and still says she's straight?
A: She's
probably a Theyfab, just
give her some time.
B: I wouldn't tell her that to her face, she gets pretty mad about it!
