There's a new photo trend spreading around social media where you try to hide all of your private parts with just one finger. Here's how it works: you take a selfie in front of a mirror, and position your index finger so it covers everything up. The trick to it is nailing the visual perspective, so you need to hold your finger pretty close to the camera to do it. It's more of a challenge for women, because your finger has to be at a perfect angle to cover up both the top and bottom.

The idea for this comes from a Japanese cartoon, where a female character did this one finger nude selfie thing. I think I still prefer the 'Mannequin Challenge.' Read more at Daily Mail and see pictures of people who have successfully completed the challenge.
