Any ideas how to subtly mention that I'm transgender in my bio?

situation is - irl best friend has my discord account added, he doesn't use discord much but occasionally and I'm just not ready for him to know yet, he's straight and not super in-tune with all of the lgbt stuff, so not 100% that he would recognize even the trans flag but i wouldn't want to risk like just the trans flag emoji, I just want to write something in my bio that can clue some people into the fact that im trans but not most

Like my pronouns on discord are "don't worry about it" lol.. *I don't know how he has no idea I'm trans by now but I'd like to keep it that way because scary*
