The 'Immortal Snail' meme stems from a hypothetical thought experiment popularized on sites like Reddit and TikTok, asking if you would accept millions of dollars for immortality on the condition that an unstoppable, intelligent snail is always chasing you, and its touch means instant death. This dark yet humorous concept gained massive traction in late 2021 as users created dramatic videos and images depicting the snail's relentless pursuit over centuries. The meme typically highlights the irony of achieving eternal life only to be haunted by a tiny, slow-moving creature that eventually becomes the ultimate threat in the distant future.
