"Naked Thursday!" is a weekly event when we as free-spirited, fun-loving people celebrate the freedom, power and beauty of the bodies that God gave us. It is designed to be liberating, stress-relieving, and borderline kinky. Recommended activities while celebrating "Naked Thursday!" include, but are not limited to dancing, singing, drinking, cleaning, facebooking, and fornicating.
I love the liberating feeling I get on Naked Thursday!

On the forth day of each week people take their clothes off to celebrate... well anything; sexuality, liberation, expression, freedom, art, beauty the list goes on.

The use of snapchat has seen a resurgence of Naked Thursdays as young adults can take creative naked pics to send to all their friends knowing that the image will only be around for a few seconds. This has lead to a series of one-upmanship where each person tries to outdo their friend's efforts from the week before.
Takin a naked pic on a exercise bike at the gym would be a great Naked Thursday snap. It's certain to beat dat cantrell playing naked golf.
