Identifying as being 18+ despite chronological age not being.
This term is already in use but I’ve never seen a coining post for it. Technically the coining definition of permadult, coined by altage, covers this, but I personally didn’t vibe with the term because for system + age regression reasons I’m not permanently an adult, plus this term is specific to chrono minors.
I also made other terms!
Transyoungadult
ALT
Identifying as being 18-25 despite chronological age not being.
There’s teleioage (20-40), flag made by transage-archive.
And there’s medioage (30-40) coined by amatorignis.
Then there’s:
Transmiddlaged
ALT
Identifying as being 40-64 despite chronological age not being.
There’s mesoage, coined by transage-page, which is apparently also middle aged though I can’t find a definition. I’m assuming this is intra-age and therefore not necessarily trans that age (as in when you bodily reach that age you (probably) wouldn’t use my term but you can still use this alt term).
Transelderly
ALT
Identifying as being 65+ despite chronological age not being.
There’s also gerantoage (60+) coined by xenoage, but again that term isn’t necessarily a trans age.
