Grumpy Cat, whose real name was Tardar Sauce, became an internet sensation in 2012 due to her permanently grumpy facial expression caused by feline dwarfism. The Christmas-themed version of this meme typically features her wearing a Santa hat or surrounded by holiday decorations, accompanied by captions expressing disdain for the festive season. It perfectly captures the Grinch spirit within internet culture, allowing users to vent their frustrations about holiday stress, commercialism, or forced cheer through the world's most famous relatable cat.
