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.
That man next door to me goes to Daytona 500, Indy 500, Coke Zero 400 and many more motor races. When he's not going to the races, he watches it constantly and never stops talking about races. He's such a raceaholic.
