The intention

of the shove (or whatever device you use) is to
trigger adrenaline in your opponent, thus hopefully
triggering his 'flight response', making him feel the urge to
want to run away. By triggering the adrenaline you
automatically trigger the 95% Rule. So, if the situation has
reached an impasse and you think it is going to become
physical, but you do not want to attack him for whatever
reason, then shove him hard in the chest, knocking him
backwards and out of immediate attacking range. This
minimal physical contact will cause an adrenal release in the
opponent. Back the shove up with a very aggressive verbal
fence, 'Stay there, don't fucking move!' Use expletives to add
intent and aggression. I feel that this is important because it
is the 'speak' of the street. If you were to say 'Damn well stay
there you cad!' it would be devoid of weight and the attacker
would probably laugh you off the planet. Speak in his
language or he won't understand you.
