Bronies are a well-known species of sub-humans that inhabit 4chan and other message boards. They are fat autists who became bored of masturbating to anime girls and decided to start fapping to the horses from My Little Pony: Friendship is Magic.
They were particularly prominent on 4chan from the years 2010 to 2013 (though, in all honesty, most of them were probably trolls) however, lately, their numbers have been declining. As of 2017, most of the remaining bronies have retreated to the Dark Corner of the Internet, where they spend their time fapping to pony porn and making outdated memes.
Kekistanis see Bronies as inferior (which we all can admit is true) and pay no attention to them. Brony memes are currently among the worst in both value and quality, effectively ending any chance of the Brony Empire rising again.
