Knew one of these had to be here...a surprising amount of bronies on this site. Anyway, some female fans prefer to go by pegasister, while some stick with brony. And yes, the pony trend started on 4 chan when someone posted a link to some guy's rant about how all cartoons were going to turn into crap designed to sell toys to impressionable kids..using mlp as an example. People actually watched the show (mostly for irony) and the fandom slowly became what it is from that.....also...stay far away from 4 chan. Not worth the mental scars it will leave.
