Popcat comes from a viral 2020 meme built around a cat named Oatmeal whose mouth was edited open and closed to make a popping noise. The format spread on social media as a clicker game and reaction image, with users competing to add more pops. The miss version plays on that expectation, using a mistimed or empty pop to signal that the click did not connect. It remains popular in short edits because viewers instantly recognise the reference and understand the failure without any explanation needed.
