 The nightcap originated as the drinks biking prevention scrunchie, a scrunchie that you can wear on your wrist or in your hair and when you go out to the bar you just take the cover out, place it over your cup and then pop your straw in there. I thought of nightcap in a dream when I was sleeping. At 16, after a friend of mine was roofied, you're not like bringing a lid out to the bar with you. You're supposed to feel comfortable and not embarrassed to go out and use it. So now your scrunchie has superpowers.
