Create a story about woman having big butts. Must explain why the preference raises the fitness of those with the preference - relating it to one of the models of sexual selection. Keep in mind that when thinking about human evolutionary psychology, the context of the life that our ancestors led (i(i.e., not our own modern culture and environment) is the best approach to take when thinking about such issues. Propose an experiment to test one of your hypotheses (either the nature of the preferences or your explanation for why females are prone to competition in a manner normally seen in males)
