Page "Passing (sociology)" Paragraph 0

Passing is the ability of a person to be regarded as a member of social groups other than his or her own, such as a different race, ethnicity, social class, gender, intelligence, age and / or disability status, generally with the purpose of gaining social acceptance.

This may take the form of changing only one group from the person's own, such as a person's dressing such as to pretend to be of a higher social class.
