Neither M-W nor Bartleby admit to any knowledge of this "word" (sic) although M-W (bless it's fuzzily logical little heart) suggests Episcopalianism, obscurantist and variations thereupon. I suspect it's a "word" (sic) that someone made up in a vein attempt to mine the possibilities of the longest vaguely pronounceable word in which all the letters are in alphabetical order.
