|1.||tin foil hat club|
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.
That guy over there is a card-carrying member of the tin foil hat club.
