Definitions of masculinity and femininity that are determined by ones culture. Therefore, the definitions of male and female can change across countries, societies, and subcultures. Together, all of these socially defined expectations make up the gender roles for masculinity and femininity. An example of gender: A tribe in New Guinea may define masculinity according to the number of elk that a tribesman has killed, while in America some might define masculinity according to how much money one makes or how much weight one can lift. (Note: as small, weak, and poor people, we here at AlleyDog.com do not ascribe to this definition of masculinity!)
