Grumpy Cat, whose real name was Tardar Sauce, became an internet sensation in 2012 after a photo of her perpetually displeased face was posted on Reddit. Her distinct facial expression, caused by feline dwarfism and an underbite, made her appear perpetually grumpy, annoyed, or unimpressed. This look resonated widely, becoming a popular meme to convey feelings of disdain, pessimism, or general apathy. Memes featuring Grumpy Cat are typically used to express sarcasm or negativity towards everyday annoyances, common frustrations, or overly optimistic sentiments, often accompanied by captions like "I had fun once. It was awful."
