The Grumpy Cat Not Amused meme features Tardar Sauce, a cat who became an internet sensation in 2012 after her photo was posted on Reddit. Her permanently grumpy expression, caused by feline dwarfism and an underbite, perfectly captured the internet's collective sense of cynicism and rejection. This variant is widely used to express apathy, disdain, or blunt disappointment toward any situation. Though Tardar Sauce passed away in 2019, she remains the undisputed queen of grumpy internet culture and one of the most recognizable animal memes in history.
