My favourite is "subfusc",
with "charabanc" in a rather distant second.
An acquaintance of mine is inordinately fond of the word "catflap".

The second defenestration of Prague (I think it was the second one) was the spark that started the Thirty Years War, one of the most brutal conflicts in human history.
