white-finned dolphin

An aquatic maneuver in which, whilst swimming under water, the swimmer pulls down their bathing suit and then surfaces only their bare ass (like a dolphin surfacing its dorsal fin) to unsuspecting fellow swimmers and beach-goers. The white-finned dolphin is ideally executed by one with the palest of asses.

"I pulled a white-finned dolphin at the beach today."

brown-finned marlin

Exactly the same as the white-finned dolphin, except executed by an individual with a brown ass.
