A common variation of this trick -which is slightly easier to perform- is for the girl to face away from the line of men, with her arms outstretched, and bracing herself against a wall with her hands.
Their aim, of course, is to pin her to the wall, but as long as she can resist the force exerted by the first man, inertia will again defeat their best efforts to crumple her... In fact, it is not uncommon even, for the entire line to find itself off balance, and falling to the floor!
We have a be nice policy.
Please be positive and constructive.
