Two or more people having sex underwater while twitching and making dolphin sounds. There must also be a trainer with a trainer stick present to properly supervise all dolphin related actvities.

General rules to follow are holding your arms like fins, doing your best to keep your legs together and playful nomming and nipping.

During the twitching dolphin you must be eating raw fish.
"it's rumored that brad pitt and angelina jolie do the twitching dolphin with angelina jolie supervising."
