Ike, what is a wingnut?
A person appearing to be moderately to severely crazy, disoriented, majobling, see Majoble, jumbled and more often than not, a total mess. A wingnut is a constant source of entertainment to those surrounding it and can easily be found in any type of setting or venue. Example: grocery stores, sporting events, cross-walks, public transportation, school, work…you may even have one in your house.
