The 'Fat Polar Bear' meme features a very chubby polar bear sitting in a relaxed posture amidst grass and bushes, looking directly at the camera. This image likely originated from wildlife photography capturing polar bears in their natural habitat, but the internet quickly adopted it due to the bear's undeniably relatable expression and body language. It taps into the universal human experience of having moments where we’ve indulged a bit too much, resulting in a content but comically overstuffed appearance.
