I know what "prendar" means, I know what "verga" means, but I don't know what this phrase means. It's from the movie, Miss Bala (takes place in Baja, Mexico, for reference), where a gang member has broken into someone's home and that person isn't cooperating as much as he would like, so he says: "¿Quieres que te prenda la verga?" As best I can ascertain, this means "Do you want me to pawn your dick?", haha. Help please.
