The Pregnant Luigi meme is a subset of the broader mpreg subculture that has permeated the internet's weirder corners for years. Featuring the beloved Nintendo plumber in a physically impossible state, the image gained notoriety as cursed content on platforms like Tumblr, DeviantArt, and Twitter. It thrives on shock value and the subversion of wholesome childhood icons. While some use it for genuine fan-fiction tropes, most of its mainstream meme status comes from users reacting to its absurdity or using it to derail conversations with sheer discomfort and hilarity.
