In a poker game, when a player bumps the bet, they increase the amount that others must call in order to stay in the hand. This is a common strategy used to either bluff opponents into folding or to build the pot when the player believes they have a strong hand. Typically, a bump occurs after an initial bet has been made, and the player wants to escalate the stakes.
Bump Example
For example, if the player before you bets $50, and you decide to bump it, you might raise it to $100, forcing the other players to either match your new bet or fold.
