Dustin, I thought you were kidding. Really? Alex, "rock throwing" has its origins with the "great" Jim Teeny. Back in the day of 3M steelhead videos, he made his name by throwing rocks at visibly holding fish; often on beds, in order to make the fish aggressive so that he could hook fish for the videos. It did work, would work, and is wrong. I won't get into the other infamous tactics used, because he's apparently a good guy and skillful steelheader (from what I’ve heard), and we all lose discretion during our 15 minutes of fame (from what I’ve heard).
