Head Hat

The act of wearing your freshly killed opponent's head on your own. Obviously reserved for the Ax Crazy types, but a few Crazy Awesome Heroic Sociopath VillainProtagonists pull it off. Two variants: Wearing the skull as a helmet, or just the skin, as a cowl/mask.

Of course, the more acceptable version uses an animal's head as a hat. Very popular among shamans.
