The Squidward Chair meme originates from the Season 1 SpongeBob SquarePants episode 'The Paper.' In the scene, Squidward excitedly brings out a lawn chair to enjoy the sun, but after seeing SpongeBob's annoying antics with a piece of gum wrapper, he immediately folds it back up and walks away. This sequence became a viral internet shorthand for expressing a sudden change of heart or a 'Nope' reaction when encountering something undesirable. It remains a staple of social media for reacting to bad takes, deal-breakers, or awkward situations.
