I’ve been fortunate enough to work in casinos for most of my adult life, both as a dealer and a professional gambler. This experience has afforded me a wealth of “industry insider” knowledge, so much so that I feel like I’m speaking another language altogether whenever I have a conversation with a fellow casino connoisseur. Between the basic terms and phrases used on the casino floor, to slang and specialized vocabulary which has been developed by players, gamblers have a whole host of code words and vernacular at their disposal.

Recently, I had the pleasure of escorting a longtime friend on their first trip to Sin City. She had never gambled before, so watching her soak in the sights and sounds of a Las Vegas casino resort for the first time was a real treat. But inevitably, I found our lines of communication breaking down whenever I lapsed into casino-speak.

When I asked her how many “cheques” she had left after dabbling in roulette, she pulled a checkbook from her purse in confusion. I told her I hoped she had a “spinner” in her next session, but she said she wasn’t planning to play the slots. And don’t get me started on “dimes,” because when I told her I bet one on the Sunday Night Football game, she laughed and offered me a handful of pennies with which to double down.

In the end, I had a blast taking my friend on a tour of the town I love most. Even so, I found myself somewhat disheartened by the disconnect between my way of speaking and the general public’s limited knowledge of casino culture. I love gambling, both as a hobby and a profession, and I consider casinos to be a combination of office and clubhouse. And like with any other club, truly enjoying the casino experience often requires players to know certain code words.

If you’re a gambler who loves the games, but doesn’t always know what dealers and fellow players are going on about, this page is for you. Below you’ll find a comprehensive glossary of terms, phrases, and slang used by casino denizens everywhere.

Action – A term used to describe having money at risk on a particular wager. When you have a sports bet pending, you’re said to have “action” on the game. Action can also be used to describe the collective wagering activity going on at any one time (i.e. “It’s been a slow week so far, but I expect table game action to pick up in the pit once the weekend arrives”).

Aggregate Limit – Used by casino operators to describe their total monetary liability on any given game type, table, or venue.

Barber Pole – Slang for a stack of chips that includes more than one denomination. Casino chips use different colors for different denominations – $1 chips are typically white, $5 chips are red, $25 chips are green, etc. – so stacking different values together creates a “barber pole” visual effect.

Another usage for “capping” is shorthand for “handicapping,” or the process of evaluating either side of a sports or race bet to determine which has the highest chance of success.
