Mickey Finn (drugs)
This article is about the knockout drink. For other uses of the term, see Mickey Finn (disambiguation).
A Mickey Finn (or simply Mickey) is a slang term for a drink laced with a drug (especially chloral hydrate) given to someone without their knowledge in order to incapacitate them. Serving someone a Mickey Finn is most commonly referred to as slipping a mickey, sometimes spelled "slipping a mickie".
History of term
The Mickey Finn is most likely named for the manager and bartender of a Chicago establishment, the Lone Star Saloon and Palm Garden Restaurant, which operated from 1896 to 1903 in the city's South Loop neighborhood on South State Street[1][2]. In December 1903, several Chicago newspapers document that a Michael "Mickey" Finn managed the Lone Star Saloon and was accused of using knockout drops to incapacitate and rob some of his customers[3][4][5][6].
