Out crazy those little motherfuckers. They must be fully aware the guy living in 1A is not to be fucked with. Go out in boxers and a wife beater with your hair all wild (will remind them of their deadbeat dad) Take their ball and stab it with a kitchen knife then throw it in a tree and then hulk up on them like what little bitches bring it. Challenge them to go tell their parent, say no one will believe little shits like you guys. You gotta speak their language.
Even if you don't have that type of crazy in you, just fake it, those kids just need to think you will lose it on them at any time, as they probably know adults like that. and they will start messing around far from your place. You must out ghetto them
