in poker, a rock is a player who plays extremely tightly, and only raises with the best of hands. although seen as better than a fish, a rock is not very highly respected in the poker community because he is too straightforward in his play.
"i just lost my bankroll to that new guy... he had aces full over sevens..."
"man, why would you call his raise? he hasn't made a play all day, he's a clear rock"
