Origin of bikiniFrench, after Bikini.
From French bikini, named after the place name Bikini, from English Bikini, the name of the atoll where the United States tested nuclear weapons in July 1946; it was reckoned that the bathing suit would cause as much excitement as a nuclear bomb. This name was originally from German Bikini, the colonial name of the atoll as part of German New Guinea, and this was derived from Marshallese Pikinni.
