Used throughout the gambling industry, the 86 casino term is one that is popular and instantly recognizable by many. Despite its widespread use, some gamblers are not aware of what the phrase means and how it may affect them. Stick around and learn some of the most important facts about the casino slang86, what are popular theories about its origin and how the phrase fits in modern casino gambling.

What is the 86 casino term?

The 86 casino term is one of the most widely recognizable phrases of casino slang in the gambling vertical. To put it simply, to "86" someone means to remove, exclude or ban that particular person from a certain casino. As part of casino terminology, the phrase is often used by casino employees, including dealers, security officials and even management personnel, when referencing individuals who are prohibited from entering the casino premises or have been removed, oftentimes involuntarily.

The 86 casino term is also sometimes referred to as "86ed," with the phrase describing basically the same thing – a person being barred from the casino gaming floor. Interestingly, both 86 and 86ed are commonly used in the broader hospitality and entertainment industry with the same meaning that a certain person is no longer permitted to enter or has been removed from a restaurant, hotel or an entertainment outlet.

Depending on the severity of the case, an 86ed person can be temporarily or permanently prohibited from a casino property. It is worth noting that the 86 casino term isn’t always tied to criminal behavior. While certain violations of the existing rules or criminal behavior may result in a person being 86ed, on some occasions, they may simply be asked to leave for the night due to their current behavior that may impact the experience of other guests.

What does 86 mean in casino?

To understand what does 86 mean in a casino, it is important to know how such establishments manage security and customer conduct. Operating as private businesses, casinos often have a specific code of conduct that allows and prohibits certain actions.

In the case that a casino patron isn’t following the established rules, or engages in unlawful activities, such as cheating or fraud, for example, they may be asked to leave or get "86ed." A casino patron may be "86ed" due to a number of reasons, including but not limited to:

  • Causing disturbance
  • Being visibly intoxicated or under the influence of drugs
  • Engaging in cheating
  • Attempting to defraud dealers or players
  • Interfering with the gambling activities of other casino guests
  • Violating game rules
  • Repeatedly breaching the casino’s code of conduct
  • Damaging property or equipment
  • Threatening casino staff or patrons
  • Distributing drugs

What is the origin of casino slang 86?

Unlike some gambling phrases, like big casino, for example, the 86 casino term has a surprisingly uncertain origin. Presently, 86 is closely associated with casinos and the hospitality industry, but some historians argue that the term didn’t originate in gambling. Interestingly, just like the phrase 86 has a numerical value, there may be just as many theories about its origin.

One of the frequently mentioned theories about the origins of the 86 casino term dates back to America in the 1920s and 1930s. According to the author Jef Klein, the casino slang 86 is tied to a bar at 86 Bedford Street in Lower Manhattan called Chumley’s. The bar in question had entrances on different streets. As a speakeasy place where alcohol was served during the Prohibition, whenever the bar was about to be raided by the police, the bartender would get a tip and tell the customers to exit on 86th Street, avoiding law enforcement, which would subsequently enter from a different street.

A separate explanation of the phrase 86, likely dating to a similar time in the United States, tied the term to the mafia days. This explanation suggested that if you want a person to get "86ed," they would be taken 8 miles out of town and put 6 feet under. A similar interpretation of the phrase suggests 86 is tied to the approximate grave size, which is about 8 feet long and 6 feet deep. While those grim explanations of the popular phrase are sometimes used, they aren’t as common as the term’s use in casino gambling.

Different theories suggest the term 86 may be tied historically to the Prohibition, the mafia, the U.S. military and restaurant industries.

Some users online suggest that casino slang 86 originated from the military. Between the 1980s and the 1990s, the U.S. military phased out the use of rotary phones. However, before that process, such devices were widely used. According to one theory about the origin of 86, the phrase was tied to "throw out," a term that was abbreviated with the letters T and O, located on the 8 and 6 dial of the rotary phone.

At the same time, 86 is believed to be related to the Uniform Code of Military Justice. Cornell Law School data detailing 10 U.S. Code § 886 - Art. 86. highlights that it refers to "Absence without leave." Art. 86. is further explained as "Any member of the armed forces who, without authority—(1) fails to go to his appointed place of duty at the time prescribed; (2) goes from that place; or(3) absents himself or remains absent from his unit, organization, or place of duty at which he is required to be at the time prescribed; shall be punished as a court-martial may direct."

A much simpler explanation of the phrase 86 suggests the term is affiliated with restaurants and bars. This popular explanation of the 86 casino term suggests that restaurant workers used "86" to note when a menu item is unavailable or is sold out. In this context, the reference for 86 was also sometimes used when removing something, like a dish or a drink.

Regardless of its precise origin, 86 made its way through the hospitality industry and has been used not only by bars and restaurants but also by nightclubs, hotels and eventually, casinos. This evolution of the popular phrase isn’t surprising, considering that casinos and hospitality businesses share operational similarities. As a result, today, casino employees often use the phrase 86 the same way restaurant workers or security personnel refer to individuals who have been removed or banned from returning to the establishment.

86 casino term in the dictionary and why does it remain relevant today?

The phrase eighty-six, or 86, is listed as a transitive verb in the Merriam-Webster online dictionary. The phrases "eighty-sixed or 86'd also 86ed; eighty-sixing or 86ing; eighty-sixes or 86es" are explained as informal verbs to refuse to serve a customer; to eject or ban a customer, or more broadly to eject, dismiss, or remove somebody. Similarly, a secondary explanation of the phrase refers to "to remove (an item) from a menu: to no longer offer (an item) to customers" and "to reject, discontinue, or get rid of (something)."

Over the last decades, the term 86 has become part of broader popular culture. Often referenced in movies, TV shows, hospitality settings and casinos, the phrase "86ed" has become synonymous with removing someone, voluntary or involuntary. Thanks to the term's widespread recognition and universal meaning, the term 86 has preserved its relevance in multiple industries.
