Some people are really into urinating on each other, but you're on the internet, so you probably already know that.  Its called Urolagnia and apparently, it's crossed over into the world of pandas.  Check these freaks out.

Alright, maybe this wasn't going down for sexual gratification, but I have to believe the panda doing the peeing thought it was just as funny as the dude filming.  The pissed on panda looks so confused, which is understandable.
