The Mocking SpongeBob meme, often referred to as Spongemock, features a still image from the 2012 SpongeBob SquarePants episode 'Little Yellow Book.' In the scene, SpongeBob mimics a chicken after Squidward reads his diary out loud. It became a viral sensation in 2017 when Twitter users began pairing the image with alternating uppercase and lowercase letters to indicate a mocking, sarcastic tone. Today, it remains the universal digital shorthand for repeating a silly statement back to someone to emphasize its absurdity.
