Selecting a timeframe in which you and your "wingmen" try to sleep w/ as many different women from as many different countries and ethnicities as possible. Each time you sleep w/ a new nationality, you have conquered that country. If the girl is not officially from the country being conquered and it's just part of her heritage, you must incorporate a physical item from that country in the act of sex to make it official (i.e. Ireland and Lucky Charms, France and wine, Canada and maple syrup, etc).
Hollywood, this is Iceman.....we need to become conquistadors for the summer and begin conquering the world one vagina at a time
