Las Vegas Lingo: 35 Terms You’ll Hear Around Your Hotel

las vegas lingo terminology terms glossary

You’ve done your research, booked your flights, and packed your bags—you’re off to Vegas baby! Whether you’re a first-time visitor or a seasoned Vegas veteran, it pays to familiarize yourself with some of Sin City’s unique terminology before you visit, especially if you’re a fish and you plan to spend any time on the casino floor. Here are 35 terms you need to know—but probably don’t—before you hit the town:

1. 86'd

Getting kicked out of a casino for cheating.

Why “86’d”?

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.

2. Beard

Someone who is betting someone else’s money on their behalf.

3. Carpet joint

A casino that caters to high rollers. If you aren’t an experienced gambler, avoid carpet joints.

4. Chalk

Vegas jargon for a favorite to win, typically in a sporting event. Usually a heavy favorite.

5. Check

In casino gambling, another term for a chip. In poker, you can check in order to stay in the game without betting.

6. Color up

When a player leaving a game exchanges smaller denomination chips for larger denomination chips.

7. Comp

Short for free or complimentary. If you spend enough money gambling (or shopping, at some casino resorts), you can get comps ranging from free meals to your entire stay. An “RFB” comp covers your room, food, and beverages.

How to get comps

You don’t need to be a high roller to get comp’d. Comps in the form of free meals, discounted rooms, or free show tickets are also available to low rollers. Rather than spending a bunch of money at the blackjack table in the hopes of getting comp’d, look into rewards programs instead - they are free to sign up for, and often come with comps included.

8. Croupier

French for “dealer”. Used in baccarat, craps, and roulette. Here’s how to pronounce it.
