Originating from Game of Thrones Season 7, Episode 3, 'The Queen's Justice,' this meme features Lady Olenna Tyrell's final act of defiance. After drinking poison, she reveals to Jaime Lannister that she was responsible for the death of King Joffrey, delivering the cold line: 'Tell Cersei. I want her to know it was me.' The meme captures the essence of taking credit for a savage act of sabotage or a petty victory. It is widely used to celebrate anonymous pranks, workplace triumphs, or high-stakes reveals where the person admitting the deed feels zero remorse and wants the credit for the chaos they caused.
