Does "going postal" mean going crazy?

Question

if not what does it mean? and where did it come from? please explain it to me. :)

Answer 1

Specifically, it means "going crazy and inflicting harm."  

Answer 2

As one who has been very close to an actual case of "going postal"... I knew both the shooter and the victim of an actual "postal" case. I can tell you that there is a lot more involved in the true "postal" situation than is commonly reported... the Postal Service management is greatly responsible for almost every case of a postal worker "going postal"....  

the term has become a common term for going crazy in a dangerous way.

Answer 3

going postal

1.

originally coined from a series of real life shootings in the postal service, it now usually means that someone is about to go nuts or off the deep end. the reason for going postal is usually trivial. also, means person on psychiatric meds that is off their pills.

after finding her computer's wallpaper had been changed again, Jane went postal on her fellow workers.

2.

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.  

Answer 4

it means extremely and uncontrollably angry, possibly to the point of violence.The term derives from a series of incidents from 1986 onward.

Answer 5

More than crazy, it usually involves lots of violence directed at those that the crazy person blames for his/her problems.

The phrase originated from the rash of post office shootings that occurred in the late 90's.  Postmen would snap, take a gun to work, and start blasting (usually co-workers and bosses).  

Answer 6

It means going violently crazy and comes from the generally well-publicized attacks that some postal workers have made on their colleagues. There's some dispute about whether this type of mass killing (almost always in the US a mass shooting) is actually more common for postal workers than for other types of jobs, but certainly there's that general perception.

"Going postal" doesn't have to mean killing; it can simply refer to an attack of wild, uncontrollable rage.
