You throw something at the next person. Simple. But, you also have to guess the next person. If you guess right, you hit them, if you don't it somehow misses. How it misses is decided by the person it misses. Example: I post: I throw a ball at "Player 1." "Player 1" posts: The ball hits me and I lose my balance. As I get up, I throw a fork at "Player 2." "Player 3" posts: I catch the fork barely an inch away from my eyes. I throw a hammer at thomaswarne. ect. Get it? I throw a 200 lb. weight at wcingisgood. (I see him a lot.)
