Fr. Tom Hopko has often spoken of the Peepees as a neat summary of the temptations of Christ in the wilderness that we must renounce if we are to follow Him: power, prestige, position, possession, and pleasure.
I see another set of adjectival Peepees lately infecting me and a lot of today's uber-Catholics: priggish, peevish, petulant, polemical, pedantic, pretentious, and pompous. These are not cute peccadilloes or personality flourishes that can be laughed off as the marks of a Chesterbellockian curmudgeon-saint. They just make us pathetic. Hey, there goes another peepee.
