The stashiani twirl is to perform the action of rubbing the end of the penis with the palm of ones hand in a 360 degrees motion at high speed at the near completion of masturbation, causing the sperm or Man Muck to fly out in a 360 degrees spread resembling a sprinkler. The aim being that it, like a sprinkler tries to cover as much as possible.
