4. Get it?
5. Here is an explanation:
Going postal, in American English slang, means becoming extremely and uncontrollably angry, often to the point of violence, and usually in a workplace environment.
The expression derives from a series of incidents from 1983 onward in which United States Postal Service (USPS) workers shot and killed managers, fellow workers, and members of the police or general public in acts of mass murder. Between 1986 and 1997, more than forty people were gunned down by spree killers in at least twenty incidents of workplace rage.
