The 'You Know Nothing, Jon Snow' meme originates from the HBO series Game of Thrones, based on George R.R. Martin's novels. The phrase is famously repeated by the Wildling character Ygritte to highlight Jon Snow's ignorance of life beyond the Wall and his general naivety regarding the world. Since its debut, the line has evolved into a versatile internet reaction used to condescendingly (and often humorously) point out when someone lacks the necessary experience or knowledge about a specific topic. Whether it's about politics, technology, or niche hobbies, the meme serves as the ultimate shut-down for confidently incorrect statements.
