it has come to my attention that at least a few people are unfamiliar with this term! It is a way for transphobic people to delegitimize and mock the transness of some nonbinary AFAB folks, particularly those who may not have medically transitioned. Unfortunately, some trans people also participate in using the term, completely ignoring the harm involved in attempting to render trans people cisgender against their will. Those people are no better than other transphobes, and I kindly invite them to fuck off. Thanks for reading!
