It's the Vegeta hairline! I got mine at fucking 26... So now I just buzz my hair super short. I definitely miss being able to grow long hair and not look like I'm completely in denial lol
It's when you.. deny something. Like you deny that you are balding here.
It's not a trans thing or anything close, but almost all trans people pass through a denial stage where they deny that they want to be a boy or a girl and say things like "well, all boys wanted to dress as a girl at least once, I just want it alot, I'm not trans"
