A slingshot swimsuit, also known as a sling bikini or mankini for males, is a type of swimsuit that stretches from the crotch, separates to cover the nipples, up over the shoulders and across the back. It can be best described as a thong that goes over the shoulders, providing minimal coverage to the wearer. Such a swimsuit can be described a having a V-front, although swimsuits that seem to be like X-top bikinis from the front with no clear indication as a bikini otherwise from the side have been described here in Danbooru as also slingshots.
A common gag is that the straps fail to completely cover the nipples.
While slingshot swimsuits are technically one-piece swimsuits, they are considered to be in their own category and should not be tagged as one-piece swimsuits.
