look up any word, like cunt:
One who is aroused by self or others in scuba equipment or imagery of scuba divers. Includes masks, fins, tanks, regulators, wet suits, swimsuits, snorkels. Often people who engage in sex underwater call it the "fathom club" - opposite of the mile high club
One who gets sexual gratification of others in diving equipment is a scubasexual.
