The 'Stannis the Mannis' meme originates from the Game of Thrones fandom, specifically referring to the character Stannis Baratheon. The nickname was popularized by fans on platforms like Reddit and 4chan who admired his rigid sense of justice, duty, and his no-nonsense attitude compared to other claimants to the Iron Throne. Common variations of the meme highlight his obsessive grammatical corrections—most famously his preference for the word 'fewer' over 'less'—and his signature stern expression. It is frequently used to represent unwavering authority, the 'correct' way of doing things, or simply to show support for the character's relentless pursuit of his birthright.
