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"
