Male who has performed anal sex
It is not the motion of the ocean. But its hard to get to Spain in a rowboat. if row boat is the size of your penis then yacht is for a bigger penis, what if you do anal? You're a dirty submarine.

The act of using your nose and face to gently burrow into the cheeks of your partner. Once inside, agressively shake your head side to side while making a propeller sound through your mouth. Imgaine motorboating in the rear.
The other day this fat chick bent down in front of me so I decided to dirty submarine her.
