Bucking in the context of "Jaripeo"

Bull riding is a rodeo sport that involves a rider getting on a bucking bull and attempting to stay mounted while the animal tries to buck off the rider.

American bull riding has been called "the most dangerous eight seconds in sports." To receive a score, the rider must stay on top of the bull for eight seconds with the use of one hand gripped on a bull rope tied behind the bull's forelegs. Touching the bull or themselves with the free hand, or failing to reach the eight-second mark, results in a no-score ride. Depending on the bull riding organization and the contest, up to four judges might judge the rider and four judge the bull on their performance. For most organizations, a perfect score is 100 points. In general, most professional riders score in the neighborhood of the mid-70s to the high 80s.
