- Or did you mean The Rock (The wrestler/actor)?
Rock is usually a heavy, natural object that you can or you can not throw. The throwability of a rock depends on the capabilities of the thrower and the size and weight of the particular rock.
Rock (or rock 'n roll) is also a genre of music.
Rock (or Seaside Rock/Stick of Rock) is usually a hard sugary stick with coloured letters rolled into the middle. They are usually found sold at a number of English seaside resorts and quite possible the world over. They are dentists' worst enemy.
