I wonder if it is a misprint for epicuricacy? Somebody's attempt to coin a word from epicurean and cacos meaning bad? So somebody treats bad events as a source of epicurean pleasure?

Edit. I take that back. From a clue in one of the pieces on Julian Burnside's site linked to by Dr. Bill, I have found in LSJ (http://makeashorterlink.com/?P229134A4 the Greek word epikairos meaning seasonable, opportune, advantageous. Kakos is the Greek for bad (cacophany). So epicaricacy could be a coinage for finding bad things opportune.
