(noun) Goth haircut where the bangs are sheared to a razor straight line with the rest of the hair long - usually black, very black. Forehead depth of line is variable, and often extreme.
The vampire mullet is also worn in increasingly, and frighteningly, large numbers by Fat-a-Billies (female rock-a-billies).
