The 'Down With Cis' meme originated from a 2015 Tumblr post where a user claimed they were attacked by a group of people wearing 'Down With Cis' t-shirts while riding a bus. The story was quickly identified as a fabrication due to its absurd details, leading the LGBTQ+ community to reclaim the phrase as a satirical inside joke. Today, the meme is used to poke fun at 'cisphobia' moral panics and often features the infamous green bus or edited images of characters supporting the nonexistent movement. It serves as a classic example of how internet communities use irony to dismantle forced narratives and urban legends.
