A ponyphile is someone who is sexually attracted to the characters of My Little Pony: Friendship is Magic and "clops" to either the official show, or more commonly, fan made material.
Brony A: Ew... did you know some bronies make My Little Pony porn.
Brony B: Yeah I know, it's so gross. They're such ponyphiles.
Brony B: Yeah I know, it's so gross. They're such ponyphiles.
