You Have Been Spooked By The Spooky Skeleton is a foundational piece of internet skeleton lore, often associated with Mr. Skeltal and the iconic Doot Doot sound effect. Emerging from early imageboard culture and popular on platforms like Reddit and Tumblr, it typically functions as a chain-letter style meme. Users are warned that they have been spooked and must share the image or reply 'thank mr skeltal' to receive good calcium and strong bones. The meme reaches its peak popularity every October during the internet's 'Spooktober' celebrations, serving as a lighthearted, absurdist way to mark the Halloween season using low-fidelity skeletal imagery.
