Extreme form of wingnut or screwball. Used of such varied figures as Timothy Treadwell, Anne Coulter or Fred Phelps, as well as countless less famous or infamous personalities.
After decades of fad diets, an addiction to homeopathy and an unbreakable certainty that the world is jointly in the hands of the Jews, the Masons, the Rosicrucians and green lizards from zeta reticuli f, you can understand that my sister is a complete wingnutscrewballsup.
