A large dinosaur, usually of aristocratic descent. They were usually seen strutting around the mountains of the cretaceous period. They often belittle other dinosaurs for not being as great as they are, even though, they are in fact far from being special themselves. They are prone to sleeping around with other dinosaurs, which causes people to associate them with the modern-day whore.
