Apart from being used as slang to refer to someone else’s appearances, the term hot is also often used in casinos. Naturally, you shouldn’t have any difficulties differentiating between the two, as their meanings are fairly different.
If someone uses the term hot to refer to a person inside a casino, they are most often thinking of a player who is on a fantastic winning streak.
The same term can be used for slot machines, blackjack, and craps tables. For example, if the slot machine has been paying out frequently, or if the players have been winning at a specific table, someone else might refer to those tables or machines as hot.
Therefore, if you’re in a casino and someone says that a specific slot machine or table is hot, they are most likely trying to give you a friendly tip and let you know where you should play.
