Counting coup was a relatively harmless act of bravery and war honor of the highest grade. Any blow struck against the enemy counted as a coup, but the most prestigious acts included touching an enemy warrior, with the hand or with a coup stick.
The term is of French origin from the noun coup (pronounced /ku/) which means a hit, a blow or a strike. The expression can be seen as referring to "counting strikes". Coups were recorded by notches in the coup stick, or by feathers in the headdress of a warrior who was rewarded with them for an act of bravery.
