where did the term slip a mickey come from
Mickey Finn (drugs) The Mickey Finn is most likely named after the manager and bartender of the Lone Star Saloon and Palm Garden Restaurant, which operated in Chicago from 1896 to 1903, on South State Street in the Chicago Loop neighborhood.[2][3][4] 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.[5][6][7][8] Moreover, the first known written example of the term, according to the Oxford English Dictionary (OED), is in 1915, which was 12 years after his trial and lends credence to this theory.
