Why does there have to be a word for that, and why does it have to be so, well, lame?
People who want to know if I like Breaking Bad never ask me if I'm a Bro-king Bad.
First of all, I'm not anyone's bro; I'm a girl. Does it say something about our society that the accepted gender-neutral term for an adult fan of My Little Pony, of all things, treats male as a sort of default?
To me it's kind of a crutch for guys who are embarrassed admitting to the world that they love something girly, for fear of ridicule, and sticking "bro" in there gives them...a sort of handhold, down into the girliness abyss.
To this I say, welcome to the sisterhood, boys. Take off the training wheels and just admit everybody's feminine sometimes.
But, yeah, I'm a My Little Pony: Friendship Is Magic fan. Of course. La la la, ponieeeeeeees <3 <3 <3 <3
