This is what me and my friends say YOLO means:
          
          "lets screw up our lives as much as we can before we die because as soon as we die we can't f*ck anything else up."
          
          I think it means:
          
          "You only live once so make it worth while, change the world and make it better, because once you're gone, you can't undo anythin gyou did while you were alive."
          
          What is your definition?
