Simpsons Lemonposting is a surreal internet phenomenon rooted in the Season 6 episode 'Lemon of Troy,' specifically focusing on the moment a Shelbyville child eats a sour lemon and reacts with a hideously puckered face. While the episode aired in 1995, the meme exploded in popularity on Facebook groups and Reddit around 2016. It evolved into a 'shitposting' staple where the lemon-eater's face is digitally grafted onto other characters, objects, or scenery, often accompanied by puns or citrus-related jokes. This trend is celebrated for its absurdity and the creative ways users integrate the distinct, wrinkled facial expression into increasingly complex and unrelated Simpsons scenes.
