Sweet Apple Massacre is a notorious 'grimdark' My Little Pony: Friendship is Magic fanfiction that gained infamy for its extreme violence and disturbing themes involving Big McIntosh and the Cutie Mark Crusaders. First appearing on platforms like Pastebin and Fimfiction in the early 2010s, it quickly became a staple of the 'shock fic' genre alongside titles like Cupcakes. In internet culture, the meme usually revolves around the visceral reaction of readers who stumble upon the story unprepared. It serves as a rite of passage for MLP fans and is frequently used in 'trauma' memes to represent the loss of innocence or the dark side of internet fandoms.
