Moirallegiance is a primary form of social relationship in the hegemonic quadrant system.[2][3] It is considered a conciliatory relation and a "red" relation.[citation needed] Exact definitions differ based on social and cultural context, but convergent traits tend to emphasize a mutual cooperation and fulfillment, non-sexual relation, and psychologically symbiotic coexistence.[4] Many moirails express experiencing a subjective "balancing" associated with their partner. Symbolized by the diamond in popular culture (stylized as ♦ or <>), moirallegiance has been a part of society for as long as recorded history exists.[5] Famous moirail couplings through history include such pairs as Mao Zedong and Zhou Enlai, Karl Marx and Friederich Engels, Suleiman the Magnificent and Pargalı Ibrahim Pasha, Rabbi Yochanan and Resh Lakish, George W. Bush and Dick Cheney, and Ben Affleck and Matt Damon.[6][7][8][9][10][11] Notable fictional moirallegiances include Mulder and Scully, Statler and Waldorf, SpongeBob and Patrick, Beavis and Butthead, and Harold and Kumar, among many others.[12][13][14][15][16]
