The 'Michelle Obama is a man' conspiracy theory, often associated with the 'Big Mike' moniker, is a persistent internet urban legend that alleges the former First Lady is secretly a transgender woman. This theory surfaced during the Obama presidency and gained momentum through analyzed photos, slow-motion video clips, and controversial remarks from public figures. In meme culture, it is used as a form of transgressive political humor or a critique of mainstream media narratives. The meme typically features zoomed-in images claiming to show 'evidence' like shoulder width or clothing folds, and it remains a staple in fringe political circles and social media discussions about deep-state secrets.
