The J.K. Rowling Tweet Parody meme gained massive traction following a series of retroactive additions to the Harry Potter universe that fans found unnecessary or bizarre. Most notably, a 2019 tweet from Pottermore revealed that before adopting Muggle plumbing, wizards simply relieved themselves where they stood and vanished the evidence. This prompted a wave of fake, photoshopped tweets where users attributed increasingly absurd or controversial 'canon' facts to Rowling. The meme satirizes the author's tendency to update her characters' backgrounds or world-building long after the books were finished, often used to mock the concept of unnecessary retconning and the 'nobody asked' nature of the updates.
