unorganized crime family
A family in which almost every member is guilty of one crime or another, and most or all were caught. A family of incompetent criminals, sad to the point of funniness.
My girlfriend is part of an unorganized crime family. Her dad's had a half dozen DUI's, her uncle is in jail for robbery, her aunt got caught with drugs, her sister got caught shoplifting, her cousin tried to steal a car, and her other cousin tries to write bad checks.
