The ducktail, also known as Duck's Ass (or in the UK Duck's Arse) is a haircut style that was popular during the 1950s. Joe Cirello, a barber from Philadelphia, claimed to have invented the Duck's Ass in 1940. A similar hairstyle, sometimes called the Argentine Ducktail, consisting of greased hair piled high on top and swept back at the sides to form a ridge or seam at the back, was simultaneously fashionable among the Mexican-American Pachucos of Los Angeles. The Duck's tail became an emblematic coiffure of disaffected young males across the English-speaking world during the 1950s.
