A form of underwear for women. Risky in the sense that some women who wear it shouldn't. Consists of an ass string and a very thin frontal portion. Worn on the right women, it is extremely sexy.
Look at that ho, she's wearing a g-string. god damn! Ass floss! Yay!

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.
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.
