Yeah it got old for me after a few weeks lol. It's a utility for me but I do smile whenever I see a trans friend be like "I love bras" 😂 get it girl. Enjoy while you still can lmao
I guess it's a typo for "baby trans", a sometimes-slightly-derogatory term (but can be neutral too) for people who only recently started transitioning or only recently realised they are trans .
Some people who've been transitioning for longer don't find the kind of stuff they feel is often posted by """baby trans""" people interesting or enjoyable or relatable. Or they just aren't into online trans meme cultures, or several other things.
This is me wearing an A cup push-up bra pre-hrt. It is nice to take off after a 10 hour day at work so I'm sure my enjoyment of wearing a bra won't last long.
