Haircut traditionally associated with American whitetrash, wrestlers, middle of the road american cockrock bands, and in general the eras of the late 70's through to the 80's.

However the mullet is currently making a resurgence in metrosexual males from the Welsh valleys.
Often associated with scarily clone-like steroid using, fake tan covered, pink t-shirt wearing posers who love themselves and spend far more time in the gym and hairdressers than any straight male ever should.
Affectionately known locally as "Spice Boys" - known more generally as "twats"
Apparently they are unaware that the mullet has not been considered cool (outside of Arkansas that is) for over 20 years
"check out the mullets on those spice boys over there - its like they're in fucking uniform man!"

"spice boys? - is that what you call them round here? - back home we just call them Twats and be done with it"

Any haircut that is short in the front, long in the back, and identified with certain regional and socio-economic norms. Usually worn by males, though not exclusively. In the USA, it is usually associated with lower education and/or income males, and often considered a sign of white trash, trailer trash or redneck status. However, in Canada, the mullet is simply known as the hockey haircut, and is a practical choice for those who play Canada's national sport because it allows the player to wear a helmet and keep his long hair.
"Whoa, check out that sweet mullet on buddy!"

A popular 1980's hairstyle that working class people continued to wear into the 1990's and 2000's, the mullet makes the American middle class feel better about themselves by giving them something to look down on; though the average U.S. citizen has a negative net worth and lives in a fascist police state controlled by transnational corporations, he can take comfort in the fact that he at least has a trendy haircut like the people on the current TV shows, and not like the people on the old ones.
Who cares about the guy who lost his job when the company built a new plant in a country where there are no child labor laws? He wears a mullet!

Any hairstyle whereupon the top is shorter than the back, and said person wearing this hairstyle still thinks that quiet riot, whitesnake, cinderella, and all the other myriad of metal bands kick major ass. Addendum to definition: People with said hairstyle usually carry with them lifetime memberships to local respective strip clubs, and believe very firmly that Pabst Blue Ribbon is STILL the beer of choice, along with Budweiser.
ANY hard rock concert will definitely prove all that I have said.
