postal

This term carries a clinical, administrative tone, evoking images of sorting centers, stamps, and government bureaucracy. It describes the infrastructure of communication rather than the act of writing a letter itself. In modern slang, particularly in North American English, the term has evolved into a vivid descriptor for extreme anger. To go postal refers to a sudden, violent outburst or a total loss of emotional control, originating from tragic workplace shootings in the late 20th century.
