an undergarment similar to a thong but has a thinner piece of fabric that lays between the butt cheeks. Whereas a thong has a slightly triangular shaped piece of fabric in the back with a width ranging from about 1 centimeter to 3 centimeters, a g-string has a very, very narrow rectangular shaped back fabric piece about half a centimeter wide. Both garments are approximately the same length in the back. The front of the g-string is similar to the front of the bikini underwear, except usually a good deal more skimpy. ***The g-string does *not*, I repeat does NOT stimulate the g-spot or clitoris in any manner, because the "string" part is in the back not the front or the inside where those areas are.***
Women buy g-strings because a g-string is useful to avoid panty lines when wearing thin and/or low-rise pants, and because some people like the look of g-strings, not because g-strings are stimulating to the wearer(They aren't.)
form of female undergarment/panties whereby the rear fabric is replaced with spaghetti string to reduce visible panty lines, and give the impression under a skirt or dress that the female is not wearing panties at all. Recently worn as bikini bottoms as exterior clothing. So named because tension on the spaghetti strap seems to be in a position to stimulate the female Graffenberg spot, aka G-spot. <-edit: that is total humbug. the g-spot is inside the vagina, on the abdominal side, about a few cm inside. It would make sense when talking about stimulating the clitoris (besides the G-spot is supposed to be a part of it), but that way it would be a C-String.
Sure, the G string on that girl shows off her ass, but look over here...gotta love a girl with guts enough to wear granny panties out to the beach.
