Is there any possibility that the Celtic queen who kicked Rome's bum ca 400 CE might be the source for the term, "bodacious?" It's a stretch (over sixteen centuries, in fact!) but is it possible?
The prevailing wisdom is that it is a portmanteau of "bold" and "audacious". I don't recommend that you believe this, but lesbian-feminist poet Judy Grahn suggests that the just-as-colorful "bull dyke" derives from Boudicca.
That would seem odd, since her rage towards Rome was ignited by their kiling her children, wasn't it? But then they claim Sappho, who, from what I've read, was a typical Greek bisexual, the norm for that culture.
