What does it mean to be a brony?

There is a difference between being a shabiki and being a brony(or pegasister). A shabiki just watches the onyesha and enjoys it, and that's fine. A brony is touched kwa the onyesha on another level, and therefore, joins the brony community. When you're a brony, friendship truly is magic. wewe help your Marafiki when they're in need, and stand up against those who try to put wewe down. wewe can have fun talking about MLP:FIM, uandishi fanfics, drawing pictures, RPing, and so much more.
That's what being a brony means to me. :)

Basically what DragonAura said.
Bronies/Pegasisters are really in touch with the show, as they know a ton about MLP and make a bunch of fanart of all sorts, like drawings, music, and fanfics. They talk about it on both internet and real life. Go to conventions like Bronycon and Everfree. Besides, it's not just those. It's believing the true meaning of friendship and happiness. Making Marafiki near au far.
