On a serious note, what general use for this except our own personal "Yay, I just took a piss here's an emote" when no-one else is going to see it(otherwise you happily announce it on the chatbox)? Or just running up to someone and doing that? In reality you would be considered a handicap and probably would be arrested nonetheless.
Or was someone watching. YOU HAVE BEEN WARNED.
