About WWI slang

Jeff Simmons

I've always found slang and its derivatives to be particularly interesting, especially those that develop during war time.

One of the most common Allied slang words in WWI was "napoo." It meant "to get killed" or "dead." It is derived from the French phrase, "il n 'y en a plus," which basically (if my translation is right) means "there is no more."

I'd like to know more of this kind of slang specific to WWI, so if you've got any words or phrases and their derivatives, I'd like to hear them. Thanks!
