rumbustious

A quick poll at this end reveals that I seem to be one of the few people who doesn't already know this word. Another clue to its common usage came when I saw it was the first of the 100 Words blogger already knew how to spell. However I'm lobbing it up anyway, even though it's not very rare, as the point for me is to learn new words. In any case, it's another lovely excitable word and I think I'll allow myself one more day of festive spirit:

rumbustious adj irrepressibly exuberant Penguin Pocket, 2004

Lovely.
