Guys are showing off their penis size in latest viral trend but the trolls are the best part

If you're getting sick of the mannequin challenge, then you'll be pleased (or not-so-pleased) to know that there's another viral trend taking off!

People have been doing the #GreySweatpantsChallenge on social media, which sounds relatively innocent. But it's actually guys posting images of themselves wearing sweatpants and showing off their penis size...

Yup, that's literally it:
