This is done when one places a Chinese whistle in their ass hole. The whistle holder is then assisted by their partner, who breathes heavily into the securely mounted whistle until maximum pressure is achieved. Then the assistant removes mouth from whistle and immediately punches the whistle holder in the belly. The force from the blow will create the
sound of a screeching locust. This works even
better when the whistle holder is wearing some
fluffy angel wings and green goggles.
