The 'He's Not Your Man' meme format rose to prominence on Twitter around late 2018 as a parody of earnest relationship advice posts. It follows a specific rhythmic structure: 'Ladies, if your man [trait 1], [trait 2], and [trait 3], he's not your man, he's [fictional character/inanimate object].' The humor lies in the bait-and-switch, where the initial descriptions are vague enough to apply to a boyfriend but ultimately fit a bizarre, historical, or nostalgic alternative. It became a viral sensation for its infinite versatility, allowing users to reference everything from Pokemon and Star Wars characters to household appliances, effectively mocking the clichés of online dating discourse.
