The mullet is a hairstyle that is short at the front and sides, and long in the back. 
According to the Oxford English Dictionary, use of the term mullet to describe this hairstyle was "apparently coined, and certainly popularized, by American hip-hop group the Beastie Boys", who used "mullet" and "mullet head" as epithets in their 1994 song "Mullet Head". The term "mullet head" had previously always or nearly always been used to refer to a person of dubious intelligence, e.g. as in the movie Cool Hand Luke, where defeated villains had been referred to as "mullet heads".
In the sixth century, Byzantine scholar Procopius wrote that some factions of young males wore their hair long at the back and cut it short over the forehead. This non-Roman style was termed the 'Hunnic' look.
The 1980s saw the zenith of the mullet's popularity in 1980s continental Europe.
In the Pittsburgh, Pennsylvania, United States, area, the mullet was glamorized by several members (including Jaromír Jágr) of the Pittsburgh Penguins (winners of the NHL's Stanley Cup in 1991 and 1992). The mullet remains popular to this day, even mocked to much acclaim by WDVE radio hosts in particular.
After the much-publicized 1992 DC Comics storyline in which Superman apparently died, the character returned in the 1993 follow-up storyline "Reign of the Supermen", in which he was depicted with a mullet. He remained with that hairstyle until 1997, and this look was depicted in an action figure released by Mattel in 2009. The cancelled Superman film, Superman Lives, depicted Superman with a mullet.
Punk rock band the Vandals sang of the mullets worn by country music singers and guests of The Jerry Springer Show and listed regional names for the style in the 1998 song "I've Got an Ape Drape".
The mullet and its associated lifestyle have been central themes in movies such as Joe Dirt "business in the front, party in the back" (2001) and the television show The Mullets (2003–2004). Christian ska band Five Iron Frenzy sang about the mullet in "The Phantom Mullet", a song off of their 2000 album All the Hype That Money Can Buy, referencing Billy Ray Cyrus and REO Speedwagon in the lyrics. The 2001 film American Mullet documents the phenomenon of the mullet hairstyle and the people who wear it.
Indie rock duo Tegan and Sara sported mullets during their The Con album era. Tom O'Neill, famed hair stylist and underwriting thief, was also known to sport the mullet hairstyle in the early 2010s.
Between 2009 and 2012, the mullet was in fashion among individuals of Lebanese descent in Australia. The style had already been popular with the bogan subculture. The fashion trend quickly waned by late 2009. This was the type of a mullet that had a crew cut at the front, top, and sides and long hair at the back.
The mullet has lowered in popularity over recent years but was recently brought back into the spotlight in 2015 by K-pop idol G-Dragon during his band BIGBANG's Made World Tour.. Byun Baekhyun of EXO also sported one in promotion for the group's 2017 song Ko Ko Bop. Other K-pop artists who have worn mullets include Block B's Zico, Song Min-ho, Nam Joo-hyuk, DEAN, Stray Kids' Chan and Han, VIXX's N, B.A.P.'s Himchan,, Seventeen's The8, BTS's V , GOT7's JB and SF9’s Youngbin.
The mullet has also experienced a revival within American sports. After winning back-to-back Stanley Cups, Phil Kessel was spotted in Pittsburgh Penguins training camp in September 2017 bringing the mullet back to its native roots of Pittsburgh Hockey. Similarly, Oklahoma State head football coach Mike Gundy wore a mullet starting in early 2017; the popularity of his mullet supposedly earned Oklahoma State millions of dollars in marketing revenue. In addition, from 2010 to 2015, Patrick Kane of the Chicago Blackhawks popularized the "playoff mullet," an alternative to the traditional NHL playoff beard.
