Mea culpa and all that. I could claim it was a test to see if anyone is paying attention, but you probably wouldn't believe me.
I found "omphaloskepsis" years ago in Mrs. Byrne's Dictionary of Unusual, Obscure, and Preposterous Words [1]. Definition: meditation while gazing at one's navel. It's not in the OED so probably wouldn't be in more quotidian dictionaries either.
Thanks for branching the forum, Nicholas. I'll link it from the Director of Time.
