The Bull Jumping Ceremony is conducted by several tribes in the Lower Omo Valley and is the most important ceremony in a tribal man's life.The ceremony is about hierarchy and membership in the tribe and typically involves a young man who undergoes a number of rituals before he leaps onto and runs rapidly over a series of cattle held by other men who have recently bull-jumped. Once the jumping is completed, the bull-jumper is a man in the eyes of the tribe. An important part of the ceremony is a ritualistic whipping, which women actively seek out from certain men known as Mazha. Dimeka, Omo Valley, Ethiopia, 2010
