Warrior's wolf tail

A warrior's wolf tail is a hairstyle used by male Water Tribe warriors. In the first and second seasons, Sokka is seen wearing a wolf tail all the time. He points out its name in The Chase, and Katara pokes fun at Sokka by saying that the style tells the other warriors that he is "fun and perky". Sokka must later give up his wolf tail for a top-knot in order to be in disguise.
