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"

1. A stone, smaller than a boulder, larger than a pebble, and is comprised of an amalgam of minerals and other organic material formulated deep within the earth's core as an initial liquid, which then exposed on the planet's surface to water, air or other cooler environments, solidifies and thus becomes a ROCK.

2. A unique combination of black soul, jazz and classical guitar that can trace genesis to the late 1940s and early 1950s, which has evolved through every subsequent decade. Modern rock is comprised of a common drum setup, a lead guitar (for harmony, riffs and solos), a rhythm guitar (for treble clef melody), and an electric bass guitar (for bass clef melody and harmonization).
-NOTE A: Often misunderstood and underestimated, rock music is unique in culture and sophistication, often falling victim to stereotypes such as "satanic", "head-banger garbage", "a bunch of screaming people throwing guitars around".
-NOTE B: Because of this misunderstanding, certain media corporations have erroniously determined rock to be a dead venue, and have moved on to another form of fad music genre that will surely fail (see Mega 101).
1. Damn, I stubbed my toe on that rock.

2. Have you heard that new rock song by Pantera?

Greatest form of music there ever was and ever will be. Despite the extremely pathetic attempt at it, some bands today are trying to keep it relatively alive, which I respect.
Fall Out Boy's "rock" may suck but at least they know what good music is. (I think)
