I just stumbled upon a great new vocabulary word while reading Programming Perl: thaumatocracy. Although m-w.com, dictionary.com, and my 2129-page unabridged dictionary all fail to define it, as best I can tell it means The elite group whose members perform magic. Used in context:

The $hints and $bitmask are internal values; please ignore them unless you're a member of the thaumatocracy.

The more I use Perl, the more I like it.
