I Sit On Acid was the first song that came to mind, but it's on the list. Others I can think of include "Pump Up the Booty" (I forget the "artist"), "Backdoor Man" by the Doors, and "A Little Respect" by Erasure. In the holiday spirit, some friends and I wrote "I Fucked Santa Up the Ass" in college, but we never recorded it, so I'm not sure that it is list-worthy.
