Pain in the Behind
A badly-timed snap or an unflattering angle can make a harmless picture into something that looks X-rated. We’re sure these two friends in the front meant no harm, and they didn’t do any, depending on how you’re looking at the picture. They probably didn’t even see what you’re seeing.
To clarify things, it’s an arm that you’re looking at and not the other girl’s backside. It’s funny how most of these epic pictures are taken when the people involved are having fun or just doing something as ordinary as taking photographs.
