The "Stupid Dumb Drooling Puzzle" meme features a crudely drawn, drooling character attempting to force a square peg into a round hole of a shape sorter. Originating from the "brainlet" or Wojak meme ecosystem, it swiftly gained traction to depict profound incompetence or a complete lack of understanding. The meme's meaning centers on someone struggling with basic logic or a simple task, often with a vacant, idiotic expression. It is widely used to mock individuals or groups perceived as making obvious mistakes, failing to grasp straightforward concepts, or trying to apply clearly incorrect solutions to problems. Its usage spans various contexts, from online debates to commentaries on everyday absurdities, highlighting situations where common sense is conspicuously absent.
