From Metafilter, 1/4/07:
Embrace the Suck. Intensive military activity creates an incubator for slang. By bringing together people from geographically diverse backgrounds, putting them into stressful circumstances, and teaching them a new language of jargon and acronym, the armed forces create fertile ground for new idioms – many of which return home in civvies when the conflicts are over. In the Civil War, World War I and World War II, in Korea and in Viet Nam, servicepeople created or popularized now-familiar terms like shoddy, hotshot, cooties, tailspin, fleabag, face time, joystick, SNAFU, FUBAR, flaky, gung ho, no sweat, flame-out, and many, many others. Now, the GWOT brings us a new generation of ‘milspeak’. Military columnist Austin Bay has published an early collection of neologisms from Gulf War II. On NPR, Bay explains what The Suck is, how to identify a fobbit, and why Marines look down on the attitude of Semper I.
I added it to my favourites, in case you want to sniff the links. Makes sense that cliques should develop jargon.
