Moxy Fruvous anyone?

I was just listening to a musical group of this name when, for some reason, it occurred to me to wonder what Moxy Fruvous actually means. Is it Latin or something?

Well, from thissite:

So, apparently, not too much.

::Once I was the King of Spain,
Now I eat humble pie…

(I love Moxy Fruvous…

If you spell Moxy as “Moxie,” you’ll find that it’s the name of a strong tasting soft drink, as well as a sort of courageous attitude.

Thanks Alice! I was just introduced to them the other night by friends and the subject of the origin of their name came up.
Great stuff! reminiscient of They Might Be Giants.
