1811 Dictionary in the Vulgar Tongue

In The 1811 Dictionary of the Vulgar Tongue, the word gormagon was humorously defined thus: "A monster with six eyes, three mouths, four arms, eight legs, five on one side and three on the other, three arses, two tarses [penises], and a cunt upon its back." The compiler Francis Grose gave the game away in his dictionary entry by explaining that it was "a man on horseback, with a woman behind him". (His "five legs on one side" description is easily explained – the woman was riding side-saddle.)
