What is a Poker Fish?

In poker and other competitive gaming scenarios, the term "fish" or "fishy" usually describes a novice or highly unskilled player perceived to be a favorable opponent. When applied in a friendly poker environment, the nickname or metaphor typically implies players whose lack of skill can lead to entertaining outcomes when playing hands, resulting in playful banter in an environment without excessive seriousness. This jovial usage reflects an appreciation for both newcomers to the game and the entertainment such players may provide to more competent counterparts.
