It is about the family problems, the father always being drunk and fighting with the mother, beating her. The father blames the mom for all problems, saying her drug use causes it but his drinking does no help either. The boy wants to lash out because he's tired of his father and his beer muscles, so after years of taking all the bullshit at home he attacks his father and they trade blows until the dad collapses, and he beats him over the head with his bottle of jack. The mother cries and can't believe it, and the boys brother is upset and says he'll make him pay in the future, while the boy just walks off and leaves home.
