rodeo event in which a cowboy attempts to ride a bucking bull while holding (with one hand only) a rope fastened about the animal's middle. No stirrups, bridle, or saddle are used. The rider is disqualified if he touches the bull with his free hand, uses sharp spurs, or is thrown from the bull within the eight-second time limit of the event. The cowboy is scored for his skill and technique, and the bull for difficulty. The two scores are combined, and the rider with the highest total is the winner
