Not only are they are queue skipper and a silent mating call, they can also be a tool of intimidation. Having a bustier cup is rather similar to the functionality of the male ego: some people find big things intimidating. Its rather marvellous, when some offensive, brash alpha is stating their claim to dominance and you display like a peacock. They dont know where to look and are aware of their presence meaning that you can speak up about your opinions and guarantee that they are heard.
