An affectation of superiority is a display of arrogance or haughtiness that often comes off as insincere or pretentious. Some synonyms for this kind of behavior might include false pride, condescension, snobbery, and a superiority complex. This type of attitude is often displayed by individuals who feel insecure or inadequate, and feel that they need to compensate for their perceived shortcomings by putting others down or acting as if they are better than everyone else. Ultimately, affectation of superiority is a disingenuous way of trying to boost one's self-esteem, and it typically only serves to alienate others and create tension in social situations.
