This photo took a very embarrassing turn after an optical illusion fail.
In the pic, a group of people are seen at the beach enjoying themselves, drinking beer and smoking cigars, as you do on a hot summers day.
But unfortunately for one girl, the photo took a very NSFW turn, and has subsequently gone viral.
Yep, an unfortunate arm position made it look like she had turned up without any bikini bottoms on, and had instead exposed a slightly wrinkly looking, tattooed bum.
To be fair, that is some pretty perfect visual trickery, so hats off to the guy and his wayward arm.
The image was uploaded to Imgur, where it’s racked up over 81,000 views.
