Where the prey (female) is sat legs apart at waist height at location A. The predator (male) at loacation B ( a point at least 5m away ) runs and attempts to "gore" the prey with his "horn". running is a must and hands may not be used to guide the "horn" or else the proper effect is lost.
Lube (remember water-based only kids) is highly recommended for this to work correctly.
The position can also be done in reverse where the male sits and the female runs. This is called Rharging Chino.
