From the medical description: St Vitas Dance - Ceaseless occurrence of rapid complex jerking movements performed involuntary Now we have all seen them in COD. The disease comes in many forms; the simplest being the desire to jump every pace into the open ground. Now this used to be called 'bunny hopping' in Quake, but in comemeration of just how stupid it looks in COD, I have now termed it 'Bunny Humping' In advanced cases you can even see the rare 'prone hopping' variant. In this case the aflicted player goes prone, jumps up, hops, lands and goes prone again. If you find yourself afflicted with this scurge seek medical help!
