When a person pulls down their swim trunks and attempts to crest the water like a dolphin breaching the surface, thus exposing their pale, white asses to the world. A variant on mooning in a swimming context.

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.
