A length of wood (roughly the length of the user's forarm) attached to a shorter length at a right angle (a bit longer than the width of the user's hand).
The common stance is to hold the shorter stick with the longer stick running along the underside of the forarm. It can twirled, used to butt at either end (enhancing punches), held and used like a club, used to aid blocking or just about anything the user can think of. Two can also be weilded. This makes it a very reliable weapon for someone who prefers to be fairly close to their opponent.

A euphemism for “kill me” now that composting oneself after one’s death has become popular.
