Transvestigating is the act of maliciously inspecting someone with the goal of outing them as trans. It is different from clocking, whereas clocking can be done without bad intentions, transvestigating is specifically done by those who are anti-trans with transphobic intent. Despite targeting trans individuals, 'transvestigations' are most commonly done on cisgender celebrities.
History
The conspiracy theory that many cisgender celebrities were actually trans emerged in 2017, and saw a resurgence in the 2020s. Pseudo-science and bioessentialism are often used as tools in 'transvestigations'.[1] Transvestigating is also closely intertwined with racism, as many features that are labeled as 'tells' are actually just features of women and men of color.
