My theory was that it surged in popularity after some major porn sites got threatened by their payment processors and decided to clean up underage and underage-adjacent videos. So people who are young enough to still live with their siblings or their parents became as close as someone could get to saying, “this person is immature and vulnerable” without getting their account moderated.

(No shade if you’re older and live with your parents, by the way. I was just referencing the stereotype)
