Passing refers to a person's ability to be regarded as part of another social group, gender, sexual orientation, ethnicity, class, or disability status. The common goal for passing is to acquire social acceptance or deal with anxiety from being different. It entails changing one or more aspects of a person. It can be as little as their clothes or mannerisms. Sometimes, as in the case of those passing as another gender or race, make-up and binding may be required.
