Paul Dickson, author of War Slang: American Fighting Words and Phrases Since the Civil War , writes that “wars create great bodies of language that sound as different as do a musket, a M-1, and a Patriot missile.” Yet while the color changes, the subjects that come in for the slang-treatment are fairly timeless: the hardship of missing a girl back home, the risks of mingling with women on the front, the necessity of facing death (often with gallows humor), and of course, the terrible food. Men with jobs far from the action, as well as those in the field who don’t contribute to the esprit de corps — self-important egoists, suck-ups, lazy loafers, and conversational narcissists — earn an abundance of nicknames as well. Finally, chaplains have long been on the receiving end of both ribbing and affection, garnering for themselves a slew of both teasing and endearing monikers.
