Steer stoppers are a type of device used to control the movement of animals, such as horses or cattle. They consist of a rope or chain attached to a post or tree, and when the animal attempts to move past the post, the rope or chain stops them. The term 'steer stoppers' is also sometimes used to refer to nooses, which are loops of rope or wire used to catch animals or people. Nooses are typically used in hunting or trapping, and can also be used as a form of punishment or execution.
