The act of riding a girl who already has a boyfriend, but shags you anyways. Purposefully getting a girl drunk who has a boyfriend for the purpose getting her into bed. Doing a chick who has boyfriend and says she loves him, for the purpose of proving she's a no good ho and giving hope to everyone who gives up when they're told "I've got a boyfriend"
That hot chick has a jockey, but I'm gonna get her wasted and steal her off him.
She's been complaining about her jockey all night, saying things aren't good, I can totally jockey steal her later.
She says she has a long term serious boyfriend, but I reckon she'll still put out.
Man, you've given hope to eveyone by jockey stealing that bird last night.
