Poker term describing a player who plays in a boring and predictable manner and is unwilling to bluff or gamble.
Typically, but not always, this player will only play solid starting hands, won't play early position without premium hands, doesn't defend the blinds, won't flat from the small blind in a multi-way pot without a decent hand, won't up the stakes in a home game etc. This person will tend to avoid gambling without an edge, whilst at the same time will take full advantage of any free drinks and/or food offered by a casino.
