This meme originates from the Season 8 episode of The Simpsons titled 'A Milhouse Divided,' which first aired in 1996. The scene depicts Bart Simpson walking into a bathroom and smashing a lightweight chair over his father, Homer, who is peacefully relaxing in a bathtub. The unexpectedness and absurdity of the act made it a cult favorite, eventually evolving into an object-labeling meme format on platforms like Reddit and Twitter around 2018. It is typically used to represent a situation where someone is blissfully unaware of an impending disaster or a sudden, aggressive interruption to their peace.
