Humpy aka Humpster Fire v4

Always a good time watching your friends make the most undignified undulations to prevent from going splat. Sit start on a grimy sloper and keep tension through edges to hit a jug. Hold the swing and find a way to mount the slopers above. There is a dignified way todo it, but most people don't find it. Pretty stiff for V4, but this is Coopers!
