The sexual act of placing a dead rodent in a condom, freezing for 3 hours, and inserting into the rectum (Usually male). Most often used in fraternities and other college parties. Very similar to the Alaskan Pipeline.
Larry: Mike, do you have any dead hamsters laying around?

Mike: Of course, my friend, why?

Larry: Do you want a 'Guilty Hamster?'

Mike: Certainly!
