Word Origin and History for go postal



"pertaining to the mail system," 1843, on model of French postale (1836), from post (n.3). Noun meaning "state of irrational and violent anger" (usually in phrase going postal) attested by 1997, in reference to a cluster of news-making workplace shootings in U.S. by what were commonly described as "disgruntled postal workers" (the cliche itself, though not the phrase, goes back at least to 1994).
