I think Mexi's point was that the word is SO incredibly outside of common parlance, that anyone who makes a point to say it instead of one of the...oh...5 billion more common synonyms, is just subtly being an asshat. I have no thoughts on the matter, but I can at least see the point.
NIGGARDLY, NIGGARDLY, NIGGARDLY!!!!!!!!!
There, I said it--a whole bunch of times. "Niggardly" is NOT a racist term. Has nothing to do with skin color, y'all can look it up, and please do. It means "miserly" or "overly cheap" or something to that effect. As an aficionado of the English language, I hate, and I mean truly hate, it when folks bastardize (you can look that up, too) the language. Not so many years ago, someone in government got fired for using the word "niggardly," and the Fourth Estate that was supposed to run herd on shit didn't figure out what the freakin' word meant until it was too late. The poor sap still ended up on the unemployment line. Again, and please, there are more than enough lawyers and academics who populate this thread. I happen to like the word "niggardly," although not as much as "nepenthe."
