Tin Foil Hat 

Tin Foil Hat, also tinfoil hat, or tfh, a general term for a piece of headgear made from one or more sheets of tin foil, aluminium foil, or other similar material. Some people wear the hats in the belief that they act to shield the brain from such influences as electromagnetic fields, or against mind control and/or mind reading. The concept has become a popular stereotype and term of derision; in Internet culture, the phrase serves as a byword for paranoia.

conspiracy theorists, whether the conspiracy is real or contrived. Usually convinced that whatever politician they dislike is a "reptillian alien" and that standard jet exhaust contrails are actually chem-trails of chemicals being sprayed down on the earth by the Illuminati.
The name originates from the belief that we are being brainwashed by mind control beams, and only hats made of foil or tin will keep the evil brainwaves out.

usually denoting some one as crazy. In later years to describe some one who usually believes everything is a conspiracy or illusion. Brought on by a belief that there is a invisible, intangible, army of Liberal Jew Communist, trying to control their mind with RF signals. So as a means of "defense" against the unreal onslaught against the LJCPMCM (Liberal Jew Communist Propaganda Mind Control Machine or media) they start covering their head with Tin Foil. Made famous by Mel Gibson, though mostly worn by the staff of the Fox News network.

Guy One: OMG, that guy must be out of his mind!
