I was watching this interview with Hey Ocean!, and this question came up at 5:58...



So apparently, one of the band members likes the show, but is more of a fan of the Bronies themselves then the show. This is surprisingly common in the Brony community. He makes up a term, calling himself a "Bro-Brony", because he's a fan of the fans of My Little Pony: Friendship is Magic.

Therefore, from now on, anyone who likes the fandom but not the actual show is called a Bro-Brony. That'll clear things up, I'm spreading the word.
