Pass is one of the most straightforward casino terms, and it is mostly heard around poker tables. The term has the exact same meaning as folding, and it is used to refer to a player who decided to forfeit their hand and stop playing in that round/hand.
While folding is used exclusively by poker players, you might hear someone else passing or taking a pass at other casino tables. However, note that the meaning of the word is the same, regardless of the type of game you’re playing, with the only difference being that it might refer to a similar action you can take.
