That night at the Brooklyn party, I was playing the girl who was in style, the girl a man like Nick wants: the Cool Girl. Men always say that as the defining compliment, don't they? She's a cool girl. Being the Cool Girl means I am a hot, brilliant, funny woman who adores football, poker, dirty jokes, and burping, who plays video games, drinks cheap beer, loves threesomes and anal sex, and jams hot dogs and hamburgers into her mouth like she's hosting the world's biggest culinary gang bang while somehow maintaining a size 2, because Cool Girls are above all hot.
