Get the Horse Chick mug.
A girl, often slender and somewhat attractive who rides horses and talks about it constantly. She'll go out with her jockey clothes on smelling like shit and buying huge bags of carrots. The typical horse chick will have a condescending attitude toward people who don't own horses.
Damn, that chicks pretty fine. What the fuck is with those obnoxious boots and leggings, though?

Man, she's a horse chick, forget about her.
