Easily the greatest strategy in Dodge-Ball. It consist of approaching the separation line between the two dodge-ball teams and frolicking like a fairy (Jerking would suffice). As soon as the other team charges you armed with a dodge-ball, retreat and wait for them to cock (haha) back their arm and throw. When the ball is thrown, fall back, and push off the ground propelling yourself backwards. Thus, Snake in the Grass.
