The mullet is a type of hairstyle that is long in the back and short in the front, which led to the phrase "business in front and party in back." This style is not common today, but it was highly popular in the 1980s.
The mullet dates back to the Vikings, Aztecs and other ancient civilizations, but no one can pinpoint the exact time of origin. The Great Sphinx has what resembles a mullet so geologists think that this hairstyle may go back as far as 10,000 years. There are several types of modern mullets with the fashion mullet being what most people are familiar with because it includes flowing hair in the back and a short, cropped style on the top and sides of the head.
