Stick-fights between individuals or large gatherings between sub-tribes where men fight duels are an important part of the anthropological heritage of various cultures, especially tribes such as the Surma people of Ethiopia, where donga stick-fighting is an important cultural practice and the best means of showing off to look for a bride, nude or nearly so, and their more warlike neighbors, the Nyangatom people, who fight duels bare-chested, the aim being to inflict visible stripes on the back of the adversary, using not plain staffs but sticks with a flexible, whipping tail-end.
