It was a racist video in which the jackass picks up some day workers in his truck and drives fast over bumps laughing about it then drives to the immigration office, starts honking the horn and laughs when the guys jump out and scatter, all the while calling them derogatory names.
The whole point of the video was to screw with these guys and have "fun" at their expense. It was sickening to watch someone actually doing this. Very stupid, very juvenile, very mean.
