pineapple upside down cake
The act of laying on one's back, while having both legs in the air (usually supported by a chair or wall), and masturbating on to one's own face.
We were hanging out at the party when all of a sudden, Spiro decided to give himself a pineapple upside down cake. He had way too much to drink.
