The Louisville Purge Hoax refers to a massive 2014 internet prank inspired by 'The Purge' film franchise, where a viral flyer claimed a night of lawlessness would occur in Louisville, Kentucky. The rumor spread rapidly across Twitter and Facebook, leading to widespread anxiety, local news coverage, and even a heightened police presence despite no actual crimes occurring. Today, the meme serves as a nostalgic reminder of early social media’s power to incite real-world panic through simple graphic design and viral sharing. It is commonly used to poke fun at gullibility or to reference chaotic, 'purge-like' energy in other local events.
