Grinch
The Grinch is a fictional character created by Dr. Seuss. He first appeared as the main antagonist of the 1957 Christmas story How the Grinch Stole Christmas!
The grumpy, anti-holiday spirit of the character has led to the term "Grinch", which is probably derived from the French word grincheux which means "grumpy", coming to refer to a person opposed to Christmas time celebrations or to someone with a coarse, greedy attitude. In fact, a document in the live-action film stated that "The term Grinchy shall apply when Christmas spirit is in short supply".
