JD Mays at Army of One points out a pretty cool site that highlights a new new word each day:
This Web site is devoted to lexpionage, the sleuthing of new words and phrases. These aren’t “stunt words” or “sniglets,” but new terms that have appeared multiple times in newspapers, magazines, books, Web sites, and other recorded sources.
Recent entries are “kitchen pass”, “RINO”, and “chronotype”. Check it out.
