The 'The Earth Is a Cup / Explain' meme satirizes convoluted internet theories and flat-earth logic by proposing an even more absurd shape for the planet. It typically features a diagram or a bold claim suggesting the Earth is shaped like a vessel—logic intended to explain why the oceans don't spill into space—followed by a demand for an explanation. This template is widely used to mock people who provide overly complex or nonsensical justifications for flawed arguments. It has evolved into a versatile format for any situation where someone presents a bizarre premise that requires an immediate, usually hilarious, breakdown of facts.
