Narsil
A title given to those who are regularly aggressive. These types usually tend to display their anger using kicks, punches, etc., usually causing the loss of friends or gaining of enemies. The term "Narsil" is also referred to as the En-Bomb (Not to be confused with the N-bomb). The "En-" stands for Energy, which a Narsil lacks most of the time.
