egregious
This is today's favorite. I like it a lot. First, I hardly know what it means (have to look it up), second, it tastes good (try it slowly, in the back of the throat) and third, it makes me feel so erudite (say it with an upturned nose).
The runner-up was 'munchkin'. The dogs liked it but the postman was less excited. He thought it was too intimate to be used for postmen. I'm going to test it on my martial arts class, too, to see if it reflects martial spirit or not.
