>>7631176Well obviously "teen" means someone under twenty, where the english word for the number ends in -teen (that's 13–19). But they can't legally film anyone under 18 (so now it's just 18–19). But producers quickly found (and rightly so) that people who want to see "teens" don't actually care about the age of the girl as long as she looks young enough to fulfil their sexual desires (perhaps it's a cheerleader fantasy, perhaps it's just that they, like all of us, are biologically predisposed to prefer younger girls). So some older (20–24 or whatever) women can pass for teens, and some are just pushing the boundaries of the word for its marketing benefit. Thus the word "teen" comes to just mean young.
As for the video you referred to, "young teen" would typically translate to ~13–15, maybe 16, but in the labelling of a video it is actually just adding tags, because not everyone that wants to see younger actresses searches "teen"; some people search "young". And so "young teen" here is just the result of an ad hoc marketing strategy.
