Loosely based on the holiday of Festivus, Grinchmas is a time to degrade and embarrass all and any who you deem deserving. Grinchmas is celebrated from midnight of Christmas Eve to 5:45 AM of Christmas morning. Social networks are commonly used to spit grinchmas venom far and wide.
Damn, did you see what was said about Mark Dorsey during Grinchmas? Poor guy's feelings must really be hurt.
