i small tuft of hair on the back on one's leg, inadvertently missed when shaving.
"While sitting outdoors at Starbucks, having coffee with my friend Cathy, i thought a small bug had landed on the back of my leg. But no. it was just my ankle-mullet wafting in the morning breeze."
A common hairstyle of an emo person, male or female - the hair is cut short and angled in the front, longer in the back, with lots of layers and rather shaggy. A variant is the reverse emo mullet (short in the back, long and angular in the front - Davey Havok of the band AFI sports one of these.)
Hair Stylist: How would you like your hair cut, Mayer?
Mayer: I was thinking of something like an "emo mullet."
Stylist: *raises eybrow*
An affliction of the upper-spine and/or neck, similar to scoliosis, resulting in a permanent bend in the neck titling the head to either the left or right. Caused by constantly straining to reach the upper rack of the fridge to get dad "another cold one" as a child.
Cletus the hoosier's dirty-ass head can be seen leaning to the right while he's driving around in his shitty old truck. The poor guy is afflicted by mulletosis, for which science has not found a cure. (Probably because medicaid doesn't cover it)
A tech savy, high scoring, gaming individual who sports the classic Mullet style hairdo ie: Business in the front, Party in the back. But in this case: Geek in the front, Gamer in the back.
Tweedle Dee: Dude! You got your ass handed to you by that geek last night in World of Warcraft!
Tweedle Dum: Yeah, I should have been more careful man. I saw he was sporting the NerdMullet!
