Transvestigation

Transvestigation is a conspiracy theory that claims many high-profile celebrities are secretly transgender. Believers in the transvestigation theory are known as Transvestigators and are known to post images, diagrams and videos online "transvestigating" celebrities, often by examining their physical attributes, to try and determining whether or not they're trans. The theory became increasingly popular online starting in 2014, when Joan Rivers joked that Michelle Obama is trans two months before her death, leading some conspiracy theorists to believe that she was killed because she revealed Michelle Obama's trans identity.
