Eighty-six or 86 is American English slang used to indicate that an item is no longer available, traditionally from a food or drinks establishment, or referring to a person or people who are not welcome on the premises. Its etymology is unknown, but the term seems to have been coined in the 1920s or 1930s.
The term has been more generally used to mean getting rid of someone or something. In the 1970s, its meaning expanded to refer to murder. [1]
There are numerous theories about the origin of the term. Possible origins include:
The term eighty-six was used in restaurants and bars, according to most late twentieth-century American slang dictionaries. [7] It is often used in food and drink services to indicate that an item is no longer available or that a customer should be ejected. [7] Beyond this context, it is generally used with the meaning to 'get rid of' someone or something. [7]
The Merriam-Webster dictionary defines the term as to "refuse to serve (a customer)", or to "get rid of" or "throw out" someone or something. [8] The Oxford English Dictionary says it may be used as a noun or verb. [2] As a noun, "In restaurants and bars, an expression indicating that the supply of an item is exhausted, or that a customer is not to be served; also, a customer to be refused service. Also transferred." [2] As a transitive verb derived from the noun, it means "to eject or debar (a person) from premises; to reject or abandon". [2] The OED gives examples of usage from 1933 to 1981; [2] for example, in The Candidate , a media adviser says to Robert Redford’s character, "OK, now, for starters, we got to cut your hair and eighty-six the sideburns". [2]
According to Cassell's Dictionary of Slang , “to 86” also means "to kill, to murder; to execute judicially," likely referring to the size of a standard grave being 2.5 feet wide by 8 feet long and 6 feet deep. [1] [9] This usage was derived from the slang term used in restaurants. [10] Other slang dictionaries confirm this definition. [11] [12] [10]
