Used as a synonym in the context of an expression equal to "not much" or "very little". Only really applicable when asked a question such as "what's up?" or "what are you doing". Based on the stereotype that the Japanese have small penises, and played on the modern response "jack shit".

Billy: That sounds pretty gay.
John: No, it is an expression. It means not much or very little.
Billy: Oh, I get it! Like a Japanese dick! HAHA!
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. See also: Beltmaster, Wifemaster, King of the Castle.
