Couple privilege is the concept that a traditional, monogamous, and enduring pair bond, typically between a man and woman, is the most significant, worthy, and desirable form of relationship. Societies may place higher status and otherwise confer rewards and recognition on this type of relationship to the detriment or outright exclude of other types of relationships.
