Passing
The ability for a person in an oppressed group to move through the world as a more privileged identity than the one they are. In BIPOC communities, passing refers to a person, often mixed-race, with features that adhere to Eurocentric beauty standards (e.g., light skin, straight hair) who may be mistaken for being white. For trans people, this means being perceived as cisgender by others.
Note: trans women perceived as women are not "passing as women" – they are women. The same is true for trans men – they are men. Passing is not a goal for all trans people but can aid in a trans person’s safety. Passing is also sometimes used to describe gay, lesbian, bi+, or ace people who are perceived as heterosexual until they disclose their sexual orientation.
