I'm pretty sure it was discussed earlier in this thread - trannies grew up wanting the 2007, hyperactive, random xd, scene girlfriend who had a homepage and spit memes ad nauseum and when that kind of girl died out (read here as became 18 ) they decided to become that. Trannies seek to become that which they hyperfixate on, but they're autistic coomers so all they can muster is a perverted, rough, facsimile of what they're impersonating. It is literally all just fetish fodder, they are roleplaying as teenage girls from the 2000's on those websites.
Edit: Didn't put a space where one was needed, as such the "18" became "1

"
