This refers to a player who calls almost every single hand.
SoundPoker Says: While some people think this is a good strategy to see the flop with any hole cards, it definitely is an expensive one. When playing against a player who calls every hand it may be wise to raise before the flop when holding a good hand. You would then be investing money into your strong hole cards (assuming your player is calling with weaker hole cards).
