Wingnut

[Sonia]

(noun) 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.

[Tina]

A name given to a person who has ears that stick out the side (at a greater angle than is usual) like little wings on their head. Sort of reminiscent of those little nuts that are easy to screw because of their wing-like attatchments, also called wing nuts.
This is how it is used by some people in New Zealand anyway.

[Tina]

A northern Ohio and surrounding areas gang of squatters, drug addicts, train [hoppers], and all-around tough motherfuckers. Will fuck you up without a second thought if necessary, but will have your back and get you shitty in your hour(s) of need. Named after the ridiculous amount of [wingnuts] found in the first factory they [squatted] in Cleveland.
In summation: Go to Cleveland, find these bastards, pull them out of whatever hole theyre doing drugs in, make them take you to their squat, and have your back covered for life.

[Raeanne Dimick]

The term is intended to refer to an irrational individual obsessed with forcing their [ideology] upon the world. The term is used most often by individuals on the left of the [political spectrum] to describe their opposition on the right.
In practice, use of this term supports the need by those on the left to rely on name-calling and taunts. This serves as a [distraction] and avoids the need to defend deeply-held beliefs with actual facts or other objectively-verifiable conditions.
