Where did the word bikini come from from?

In May 1946, he advertised the bathing suit, known as the "Atome," as the world's "smallest bathing suit".

Réard named his swimsuit the "bikini", taking the name from the Bikini Atoll, one of a series of islands in the South Pacific where testing on the new atomic bomb was occurring that summer. Historians assume Reard termed his swimsuit the "bikini" because he believed its revealing style would create reactions among people similar to those created by America's atomic bomb in Japan just one summer earlier.
