Fem9boy
Fem9boy or Femi9boy/Femnboy is short for feminine boy, a contraction of the word "fem" & "nine" from "Feminine". The "9" in Fem9boy/Femi9boy is not meant to be a censor (numbers are usually used to censor letters but not in this context) It is genuinely just meant to make the word shorter & for those who refuse to type the whole thing which is "feminine boy".
This alternative term was made because the combination of fem & boy could be seen as offensive by/for trans women since the fem can also mean female boy instead of feminine boy (both of them are still derogatory if used against trans women) & the alternatives for feminine boy is a combination of rose & boy or rosboy which was rejected by & also seen as derogatory by the Feminine boy community.
But not all trans women think the combination word of fem & boy is offensive (unless used against them) & not everyone from the Feminine boy community think the alternatives for feminine boy are offensive. The term Fem9boy is just optional for those who want to refer a feminine boy without possibly offending anyone & prefer typing a shorter term because it's much easier.
