machismo

n. assertive masculinity which is often characterized by aggressiveness and dominance over women, male chauvinism, quality of being macho

Machismo is a prominently exhibited or excessive masculinity. As an attitude, machismo ranges from a personal sense of virility to a more extreme masculism. In many cultures, machismo is acceptable and even expected. The trait may be seen as the product of runaway evolution, as Frits Staal notes,The peacock's tail, the grotesquely enlarged claw of the male fiddler crab and the machismo of members of the human species are all exaggerated features that may cause injury to individuals that display them but attract females.
