"New rule: anyone who uses the word "corporation" in a debate has to define in within 15 seconds, or else forfeit entirely." --Adam "Rutskarn" DeCamp, via Twitter.
Good rule! Mind if I add a few words to that list? "Empire", "imperialism", "capitalism", "liberalism", "conservatism". The first two have some fairly specific denotations which tend to get lost in transcriptions, and the last three will change with time and place (e.g. P.J. O'Rourke's notes that American Capitalism = Wall Street and Albanian Capitalism = pyramid schemes). Any other words I should add?
