The Frank Heffley Schizophrenia meme stems from an edited scene in the Diary of a Wimpy Kid film series, depicting Frank standing alone with a vacant, traumatized expression. It belongs to a subgenre of internet humor that takes lighthearted children's media and applies 'schizoposting' or psychological horror elements to it. The meme usually implies that Frank’s family is a figment of his imagination or that he is dealing with deep-seated trauma, often accompanied by captions telling him the 'accident' wasn't his fault. It gained significant traction on platforms like TikTok and Reddit as part of a trend of making liminal or cursed versions of nostalgic movie characters.
