Reportedly, this man went out of his way to come to this house and once he was there he started talking trash.
Based on the events in the video, it appears that the home's residents try to passively dismiss the trash-talker by gently shutting the door. However, when that didn't produce the desired results, the situation rapidly escalated into a physical fight.
It ends with the first man nursing a bloody face.

Maybe this is a lesson about resolving your problems in more constructive ways than going to people's houses and talking trash.
