Someone who feeds on expressing rage. Like the alcholic, the rageaholic is addicted to blowing up. This is usually caused by the rageaholic stuffing back real feelings and emotions until it builds up the point that the rageholic snaps and goes crazy. Stress of any kind can be a trigger. It is a cry for love, but a fear to accept it.
Greg is a recovering rageaholic, be nice to him.
