The group included four "Pegasisters," as the small minority of female bronies sometimes call themselves in this male-dominated world.
2012, Reed Tucker, "Horsing around!", New York Post, 11 January 2012:
“I’d say 80 percent of my friends are into it,” says the “pegasister,” slang for a female fan. “My dorm loves it. We get together to watch the shows, and we eat and laugh.”
Together with their female counterparts, Pegasisters, they have fan sites, conferences (BronyCon), and an incredibly persistent meme that permeates popular websites such as 4Chan and Reddit.
