When you have your towel tied around your waist and you un-tie it. It doesn't fall down so you perform a hands free towel shimmy.
This morning I had a shower, afterwards i was getting dressed. I had my towel around my waist, and my phone in my hand texting a friend. In order to take my towel off i needed to perform a hands free Towel Shimmy, Afterwards i felt majestic as fuck.
