I'll relate what I did in a little while as I'm curious how others would react.

fenriq, when did you move to the Mission?

Heh. This was somewhat common for us when we were living in the French Quarter in New Orleans. We basically just walked out and said "this someone's house, you idiot; you're pissing on our house!" The neighborhood was tight, so the neighbors would usually come out and boo them off, too. Helpful with belligerent-drunk 300 lb. fratturds - usually there for Sugar Bowl or Mardi Gras.

Balcony apartment is the way to go. One street-level place I lived, people would actually walk through the front gate, up onto the porch, and try to peer through our windows. So many tourists couldn't get it through their heads that it was actually a living community and not a Disneyland-type place.

Electric fence.

ha!

Frisbee Girl, I'd expect it there, not where I live now.

Sneak around the back and collar him, of course.
Unless it looks like he has a gun, then I'd just throw stuff out the window at him.

I walk over and piss on his leg.

Hugh, don't you think some sort of escalation is in order though? I mean, I don't know what the next step would be, but...

I'd set the hose to high pressure, scream "bidet!" and aim it up his ass.

Shout at them while they are doing it. It is hard to stop in midstream, without pissing on your pants or shoe.

Or, point and laugh.

I've wired 9 volt batteries to the steel grate they piss on in my house. The damn landlord keeps removing it though.

true story: This Church is Stockholm has the unfortunate location between all the late night bars. It also has (like so many churches) a small area as an old graveyard. Being in the centre of the bar area, and "private" in that it was dark and had trees it was a great place for drunk guys to go and relieve themselves.

One night a man went up there, like so many did, and pissed against the church wall. A gravestone behind him decided to suddenly uproot just a tad, and tipped over, jamming the peeing man between the stone and the wall.
He stood there hollering for help all night, until someone found him the next morning.

"Some people God punishes immediately" like my mum says. ;)

Okay, let me fill in some of the blanks.

First off, I was alerted to him there by my dog who was going absolutely ballistic in the front window. This is not a lapdog, this is a 95 pound dog with a pretty ferocious bark.

When I saw this PoS, I ran out my front door and charged him. Pushing him and shoving him and shouting at him the whole time and got him away from my house.

He actually threatened me while doing this (hard to be a tough guy with your dinky dink hanging out though) and popped his around the corner after I'd gone back inside to get his last word in (flipping me off).

He went back next door and then left pretty soon thereafter. A few minutes later, one of the kids from next door came over and apologized for the guy's obnoxious and rude behaviour. Which was a really nice gesture. If he'd stepped towards my front door again, I was more than ready to go and bring a beatdown on his ass. I didn't punch him the first time around but I was furious and I'm not the most rational guy when I'm thoroughly pissed off.

But now I'm somewhat justifiably paranoid that this punk kid is going to come back and try to re-inflate his pride by escalating the issue. And if he came looking for trouble, I don't know what I'd do. I'm a generally non-violent guy but I really do not put up with crap like this at my home.

Needless to say, I'm very much looking forward to selling this house and moving to much more private surroundings where we do not share a driveway and can't even see our neighbors.

dabitch, I bet he had to change his shorts and not because of pee! Great story!

Talk to the landlord next door. If this guy's pissing on your house, it's a certainty he's been doing stuff just as annoying to the place next door -- no respect for property, well, that travels. There's a halfway decent shot the landlord will suddenly come up with a good reason to kick his ass out the door.

In the interim, put up a NO TRESPASSING sign. It's incredibly legally helpful if you have to call the cops on him. You'd think it wouldn't be necessary, but areas outside a house are semi-public.

Fenriq, if his friend next door came over to apologize, then the guy has no backup. He may not be brave enough to come back if he knows that no one has his back.

stilicho, he doesn't live next door, he was visiting one of his pals who lives next door (and wasn't home). And the dad next door does not like this kid to begin with.

I was going to talk to him about it yesterday but I couldn't get a minute with him alone. I would imagine he won't be coming around ever again once he hears about it, he doesn't put up with crap like that either.

If I knew the kid and he was pulling this crap, I would have pounded the snot out of him.

jrossi4r, that's likely true. And my (first line of) backup is a damned scary hound.

Great, you have a dog. Next time, go up on the roof and drop big clumps of dogshit on his head. Then cackle gleefully as he tries to wipe the smell away.

I think I would have gone with the "DUDE, you're pissing on my HOUSE" approach, myself.

kmellis, I did do that but I combined it with shouting and shoving too. And I'm pretty sure dude pissed all over his shoes and maybe his pants too.

There is a sports complex (several baseball fields, soccer fields and tennis courts) across the street where the little league and hispanic soccer leagues play. People are always throwing out cigarette butts and the like and I pick up literally dozens of them some weeks in the summer months. You can't really catch people doing that and if you do, it is hard to do much about it. But one day I was working outside behind a Japanese maple tree and large rock near the road. A guy threw a bottle out and it landed next to me without breaking. Without thinking I picked it up and threw it at him as hard as I could. Went in the open passenger window. They just drove off really fast. I was worried they would come back angry, but perhaps they were too scared. Who knows, maybe they didn't even see me and were totally freaked out that the litter bounced back at them. *shrugs*

I would've hosed him off. Garden hose, that is.
