The "Mocking SpongeBob" meme features an image of SpongeBob SquarePants in a distorted, exaggerated pose with his face twisted and eyes misaligned. Originating from the Season 9 episode "Little Yellow Book," this meme is used to sarcastically mock or imitate someone by repeating their words in a distorted, childish tone. The format typically involves alternating upper and lower case letters to represent the mocking tone. It gained popularity in 2017 and has since been widely used across social media platforms to convey a sarcastic or condescending response to various statements or opinions.
