1) In a general sense, it can refer to an unbroken or wild horse that is difficult to handle, especially in the rodeo events such as bull riding and calf roping.
2) It can also be used to describe a type of vehicle, particularly an old pickup truck, which has been modified for off-road driving.
3) In some regions, it is used to refer to a small town or city in the American West, often associated with cowboy culture and ranching heritage.
