According to the official version, the modern bikini was invented by French engineer Louis Réard and fashion designer Jacques Heim in Paris in 1946 and introduced on July 25 at a fashion show at Piscine Molitor in Paris. It was a string bikini with a g-string back. It was named after Bikini Atoll, the site of nuclear weapon tests a few days earlier in the Marshall Islands, on the reasoning that the burst of excitement it would cause would be like the nuclear device.

Burping, also known as belching, ructus, or eructation involves the release of gas from the digestive tract (mainly esophagus and stomach) through the mouth. It is usually accompanied with a typical sound and at times an odor.

The noises commonly associated with flatulence are caused by the vibration of the anal sphincter, and occasionally by the closed buttocks. The sound varies depending on the tightness of the sphincter muscle and velocity of the gas being propelled, as well as other factors such as water and body fat.
