Top definition
A system of social mores that finds it not only acceptable but necessary to exact a broad array of punitive measures against an individual or individuals for heinous grievances such as defacing the Terrible Towel, stealing a parking spot saved by a parking chair, etc.
In a clear example of yinzer justice, the car was encased in a two-inch think layer of ice, courtesy of a old lady and her garden hose after the car's owner moved an old lady's parking chair and took her parking spot. The Pittsburgh Police have thus far refused to comment on the matter.
