what is a cooler in poker

In poker, a cooler is a situation where a player with a strong hand loses to an opponent holding an even stronger hand. It is a "bad luck" hand where a players strong hand unfortunately clashes with an opponent holding something even better. A cooler is not a mistake made by the player, but rather a result of the way the cards came out. It is a common occurrence in poker games and can be frustrating for the player who loses the hand.
