It's always been a thing (girls liking it, I mean...not touching the 'gay acting' part) I just think now with the interwebs and tumblr and everything else, the fangirls are just more vocal about loving it. Also, we're more aware of how celebs are acting...(not that boys liking to touch each other is new; anyone with a brother/multiple male friends/is a boy can tell this) Back in the 90s I knew nothing about BSB unless it was in Pop or Teen Magazine...
