Well I'd just go chill in this B kid's bushes until his brother came home. When he did I'd tackle him and bash his face into mush, then cut his ear off and give it to his lil brother to remind him that next time he should fight his own battles and not cry to big bro because he can't hear you anymore.
Done and done.
WOO TENG CLEN AINT NUTIN TO FAK WIT
but seriously that sounds bad. Did he start the fight? Get some bigger guys (maybe with guns) with you and then talk it out. They won't dare to do anything to him if you're atleast as much guys as them.
