Affected mannerisms refer to an individual's behavioral quirks or habits that are artificial or exaggerated for the purpose of creating a particular impression. Synonyms for affected mannerisms include affected behavior, affected style, affected gesture, affected posture, pretentious mannerisms, ostentatious mannerisms, artificial mannerisms, and affected eccentricity. These synonyms all refer to the same behavior where a person is putting on an act of being intentional with their behavior than being themselves naturally. Such mannerisms may be perceived as insincere or disingenuous, and they may become a barrier to authentic communication and genuine connections with peers and colleagues. No matter the word used, affected mannerisms always imply that a person is trying to be something they're not.
