What is Curb Job?
1.
It's a little more involved than simply banging someone's head against the curb. It actually means to force someone to lie down, open their mouth and bite down on the edge of the curb, then you stomp on the back of the person's head with as much force as possble(presumably breaking the person's lower jaw clean off or even cause death). I've heard the term used as far back as 1993.
You can see an example in the movie "American X".

I am sure it existed before the song but on the album "The Incredible Shrinking Dickies" in 1979 there is a song called "Curb Job" as far as I remeber it was always a skinhead thing where a person bites the curb and has the back of there head stomped- and would be shown in the film American History X many many years later
