Kids outside house

Pay some bigger kids to come buy and give them a beating.

Sell them Drugs.

Hose them down. Preferably from inside an upstairs window.
They will run away and be pissed, and probably come back to throw rocks at your windows. But if you hose them down with a watergun or hose every time they kick the ball at your windows / car, they wont come back. I did this a couple of times years ago with some kids in my neighborhood.

tldr: blast em with water / piss

I've a few ideas. You can try them separately....or all at once, or mix and match. It's up to you. Not sure of the effectiveness either way.

1. Play music out onto the street. Either classical music, something like The Four Seasons violin concertos by Vivaldi or maybe a mixed play list of songs by well known gays, The Village People, Elton John, Justin Beiber etc. With the classical option they might just find it really annoying and fukk off, with the gay option they might be too embarrassed that people they know will walk past and see them all running around exercising to YMCA and fukk off.

2. Get a few of you mates to come around at night when they are playing and all sit there in your garden on deck chairs having a few beers. Alternate between cheering them on and clapping far too enthusiastically whenever they do something good and laughing and shouting "Taxi!" whenever one of them scuffs a shot or falls on their ass. They will dislike when either is done.

3. Get a borrow of some pretty teenage daughters from your friends or neighbours. Pay them a tenner each to come and watch the lads playing for 15 or 20 minutes and then to start commenting to each other overly loudly that football is really gay and they reckon only homosexuals play it so they get to get all sweaty and hug each other when they score a goal.

4. Go to your nearest Traveler site with 100 euro and buy a few dags. Ask them for right vicious little bastards cause you want to put them in the fights. Release them mid game.
