Leave it to Japan to improve on a task that you probably thought you had mastered. By assigning the term ‘the forgotten orifice’ to the belly button, product maker Sosu has given this unlikely anti-hero just the right amount of sympathy to make it appealing. Just apply a dot of the supplied gel to the tip of the swab and after a quick run through your belly button, you’ll be ready to dole out the body shots with reckless abandon. And in case you’re wondering how in the world they came up with this name, having sesame seeds in your belly button is slang for belly button lint.
