Emotional repression

Females know males never thought they were more emotional than males, its why they often try to tease males when they get emotional about something, and females do this often. Not displaying emotions is emotional repression, whether its males doing it, or whether its females doing it. Emotional repression is why some females try to come off as tough and badass as a defense mechanism to perceived (or real) bullying, and by being defensive, they're less likely to come off as the bully themselves.
