Chrisanthropy
Contempt for humanity provoked by exposure to the trappings of Christmas (e.g. crowds of shoppers, TV advertisements, endless rehashing of festive hits on the radio etc). A portmanteau, formed out of the words "Christmas" and "misanthropy".
Seeing the Coke ad filled Manfred with deep feelings of Chrisanthropy. He was later arrested for assaulting a department-store Santa.
