There is no definitive answer to this question as it can vary depending on the specific situation. However, generally speaking, it means that the dealer has determined that the player is attempting to cheat and is therefore breaking the rules of the game.
This could involve anything from counting cards to tampering with the deck. In some cases, it could also mean that the player is simply playing too aggressively and is not following the basic rules of the game.
If a player is caught busting in blackjack, there are usually consequences that will be levied against them. This could include a loss of money, a suspension from the game, or even a ban from participating in future sessions.
In some cases, players may also be subject to criminal charges. It is ultimately up to the discretion of the casino staff as to how they choose to handle busting in blackjack incidents.
