Look up count coup in Wiktionary, the free dictionary.
Among the Plains Indians of North America, counting coup (/kuː/) is the warrior tradition of winning prestige against an enemy in battle. It is one of the traditional ways of showing bravery in the face of an enemy and involves intimidating him, and, it is hoped, persuading him to admit defeat, without having to kill him. These victories may then be remembered, recorded, and recounted as part of the community's oral, written, or pictorial histories.
