moonbat

From moon +‎ bat, first used in the 1940s by the science-fiction writer Robert Heinlein[1], then used in the term “barking moonbat” coined in 1999 by Perry de Havilland of “The Libertarian Samizdata”, a right-libertarian weblog. This originally referred to both left-wing and right-wing crazy people.[2] Sometimes wrongly claimed to be a corruption of Monbiot (from George Monbiot, British environmentalist and Guardian columnist).[3]
