The Great Mighty Poo first appeared as a boss in Rare's Conker's Bad Fur Day for the Nintendo 64, where Conker faces him in a sewer level and the boss sings an operatic song about himself while throwing dung. The character became a cult favourite because the polished opera style clashed so sharply with the crude premise, and clips of the song spread through gaming forums, YouTube compilations and meme soundboards. It remains popular today as shorthand for mock-grandiose villainy and gross-out humour in edits and streams.
