A miss is when a player fails to make a drawing hand with the cards dealt on the board. It can be used to refer to not making a hand on the flop, turn, or the river.
Miss Poker Example:
Let’s say a player has a Kc Qc hand, and the flop brings 4s 3s 2s on the board. They completely missed the flop, as their hole cards haven’t improved at all.
A similar example can be applied for failing to improve a hand on the turn or river. For instance, a player has a 9 8 hand, and the board after the flop is Q J 5. Then, the turn and river bring up an A and a 4. They have missed their inside straight draw on both the turn and the river.
