The lyrics and video are quite comical because they are so obviously about sex. Warrant got away with it because the sexual imagery had double meanings - there was no way to prove that they weren't singing about an actual pie.
The woman in the video was briefly married to lead singer Jani Lane. Her name is Bobbie Brown, and she became one of the most famous video vixens of all time. She went on to a few acting roles, including movies The Last Action Hero and Kounterfeit and TV shows News Radio and Married With Children.
