A rattail is a hair style that is characterized by a long "tail"-like element of hair growing downward from the back of the head. The rattail usually hangs naturally; however, it can be braided, treated as a dread, permed, straightened, or poofed, curled with an iron. In some instances, an individual might choose to grow several tails as opposed to a single very long tail.
Some punks and rivetheads have been known to sport them also, although in a much more punky style, totally shaven head, except for a tuft of hair at the back, usually dyed in various luminous colours. It is a very popular hairstyle in New Zealand, especially among boys, and is sometimes combined with shaven sides, a soft mini-mohawk and 'tram tracks' in Maori designs.
In Disney's 2002 animated feature Treasure Planet, Jim Hawkins sports a rattail throughout the movie until the end.  In the 2016 film American Honey, Shia LaBeouf's rattail garnered critical praise. In the 2017 film Wonder, August "Auggie" Pullman has a rattail during the beginning of the movie, until he cuts it after he gets made fun of it.
