Do you use a Thesaurus, or something, or are those words just a part of your normal vocabulary?
Flat-out part of my normal vocabulary. I was an English major for a while. I love me some ten-dollar words.
When's the last time you used either of those words?
At EvC? November 2007 was the last time I appear to have used "opprobrium", and June 2005 was when I last used "pusillanimous." According to the search.
