86 (term)
Eighty-six or 86 is American English slang, generally meaning to "get rid of" someone or something.
In the hospitality industry, it is 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.
