Semi-derogatory term used by professional gamblers to describe just another sucker at the casino. While professional gamblers are at a blackjack
table counting cards, the "ploppies" are the players at the
table who the casino loves because they play the
game at an average level (or below) and just don't know any better. Sometimes ploppies can get in the way of the professional players.
