16.
A men's exhibitionistic garment consisting of a pouch and over-the-shoulder straps. Usually thong backed or nearly so. Can be marketed as either beachwear or underwear. An earlier definition of banana sling seems to describe a slingshot.
Koala once described a slingshot as the world's highest cut bathingsuit.

17.
Post-coital flinging of the spent condom in the direction of the female as she exits the room, with malicious intent to hit her in the back. If done correctly, she will yell in pain and embarrassment.

18.
A flimsy undergarment for women, otherwise known as a g-string, thong or as my father likes to call them, "butt floss."
I won't let my dad see my doing my laundry because he refers to all my underwear as slingshots.
