Picture This guy Lavaliered and got shit piss and gallons of dip spit poored on him, he really loves his girlfriend. notice the guy peeing on the back of his head. (Warning: This is the grossest thing ever.)
Picture I can only get sexually excited when I'm in public, and I'm peeing on a girl, and there's an animal, and my friend's taking a picture.
Picture If people are pissing on the door (and occassionally in your room if you're not there) this sign isn't going to help.
