The 'S Stands For' meme originates from the opening theme song 'Bon Appétit ♡ S' of the 2017 anime Blend S. The intro features the main characters being categorized by 'S' traits: Smile, Sweet, Sister, Sadistic, Surprise, and Service. In late 2017, the internet began creating parody videos and image macros where the final 'S' (Service) is replaced by an unexpected word or character, often accompanied by a drastic shift in music or tone. Popular variations include 'Snoop Dogg,' 'Skyrim,' and 'Soviet Union.' It is widely used to subvert expectations by leading viewers through a cute anime intro before dropping a jarring, loud, or weird punchline.
