The G String.
The G-string style consists of an elastic string - as opposed to a strip of fabric - connecting the front/pouch and the waistband in the rear. It is also called a Rio thong. Since the mid 1920s female strippers and erotic dancers in the west have been referring to the style of thongs they wore for their performances as G-strings. The origin of the term "G-string" is obscure. Since the 19th century the term geestring referred to the string which held the loincloth of American Indians and later referred to the narrow loincloth itself. William Safire in his Ode on a G-String quoted the usage of the word "G-string" for loincloth by Harper's Magazine 15 years after Beadle's and suggested that the magazine confused the word with the musical term G-string (i.e., the string for the G note). Safire also mentions the opinion of linguist Robert Hendrickson that G (or gee) stands for groin, which was a taboo word at these times. In Israel the G-string is called khutini (חוטיני), from the word Khut, which means String. In Lithuanian it is siaurikės ("narrows"), Italian perizoma, in Turkish ipli külot ("stringed underpants"), and in Bulgarian it is known as prashka ("slingshot"). A frequent metaphor, especially in South America, is dental floss as in Spanish hilo dental or Portuguese fio dental. A Puerto-Rican Spanish slang term, used by Reggaeton artists, is gistro. In Argentina the most common name for thongs is colaless or cola-less originated by an article publish by GENTE magazine in the 80's. The origin is probably connected to the term topless but in reference to cola (butt is spanish).
