The mile-low club is slang for the people who have had "sexy times" on board a sea vessel submarine.

An alleged explanation for wanting to perform the act is the supposed depth of the experience. Some say they have fantasies about Aquaman or mermaids, or a fetish about the sea themselves. For others, the appeal of joining the mile-high club is the thrill of doing something taboo and the thrill of the risk of never being discovered.

History
The idea germinated pre-evolution, as life started taking form. Remember, we all came from the ocean.
