Used to describe the level of anger a Stepfather may have against a child or woman. The rawest form of anger, untamed and furious. When one is overcome with Stepdad Madness, they may exhibit a skin color similar to the blood that was about to be shed, visible veins in the face and may also be prone to using a bottle of alcohol or belt as a weapon. They may also yell in profane absurdities, say that it is someone elses fault, and destroy property as well as people, both physically and emotionally.
