You know how everyone who went to Vassar is all, "one time, when Annie Hathaway and I were studying for our intro to lit theory final..." and you have to control yourself from punching them in the face? With that in mind we decided to ask our friends in high places to help us compile an insider's guide to celebrity nicknames, so you too can be "that guy" at a cocktail party (or Sundance premiere after-party?) going on about "how cute Katie Heigl looked in the trailer for One for the Money." You're welcome.
