English slang term applied to anyone who makes a name for himself denouncing others for being racist or sexist and then, hilariously, ends up getting denounced for the very same things- with the added suspicion that he may be kind of a perv. Used to be called getting 'hoisted by ones own petard' or 'poetic justice'.
