Johnny The Homicidal Maniac's definitions
Basicly, "going postal" is pulling a uzi, assault rifle or most any other firearm out from under your jacket and going nuts. That is, wasting anyone and anything you see, and then probably yourself. A bit like going apeshit.
Jim had left another burning paper bag of crap on John's doorstep, so John retaliated by going postal on his ass.
