There are several possible origins to this term:
- US Navy decommissioning: After WWII, a large amount of warships were being decommissioned, scrapped, or sold and placed in reserve. In the process, workers would bring spare parts from storerooms. Anything that was to be disposed of was given the US Navy Allowance Type (AT) code “AT-6”, pronounced the same as the number 86.
- 86 Bedford Street: 86 Bedford Street was the home of a famous speakeasy in Manhattan’s Lower East Side. Some reports suggest that police would call the bar during prohibition and advise patrons to leave via the 86 Bedford Street door, while the police would enter through a different door.
- John Barrymore: According to the Oxford English Dictionary, the first recorded usage of “86’d” as a term for refusing service was a 1944 book about John Barrymore, who was infamous for his drinking habits. Apparently, John Barrymore was known to a particular bar as an “eighty-six”, which in the vernacular of the time, meant “don’t serve him”.
- Electrical Protection: In common terms, an 86 device “locks out” a piece of electrical equipment, meaning it turns the equipment off until the appropriate person can resolve the issue and reset the 86 device.
