What in the World?

So my BF and I went for a walk downtown on Saturday and somehow found ourselves behind this guy, who had....well, we are still not sure what exactly, hanging out of the back of his shorts. I don't have much experience in identifying man thongs (lol neither does my BF), but I think that's what this was. I have no idea why it was on the outside of his shorts, or how it was staying put there, and I couldn't (and wouldn't want to) even hazard a guess as to how they got there in the first place. But what else could it be? Some kind of new belt? Or a really poorly constucted fanny bag? There was an air of mystery surrounding it for sure, and unfortunately that mystery was never solved. What do you think?
