I'm pretty this has already been a topic of discussion, but whatever.
I prefer brony, if I need to use any kind of label at all. I mean, I like animation. I may or may not aspire to be an animator. I don't care about the intended demographic... all lot of kids shows appeal to adults, though, in my opinion.
Anywho...
Yeah, pegisister is a word, but I never cared for it because it's exclusively associated with the word Pegasus.
I really don't think any girls care about the male association with the word "bro", sooooo... Who cares?
