When an individual is held down against their will whilst an agressor positions his buttocks either side of the poor soul's nose. The "crack" is then rubbed up and down the face in a straight line, mimicing the movement of a monorail.
The group thought it would be funny to take Ed down a peg or too, so they held his arms and legs in order to allow Rhodri to monorail him.
