Top definition
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."
