Rimfiring is a hazard in the work of a cowpuncher. Once a horseman has roped a bovine, he must be careful that he doesn’t rimfire another horseman near him. He must control the bovine he is tied to. If a roper lets his catch wrap another horseman in the rope, he rimfires that other horseman. No matter how gentle a horse is, he will explode when rimfired. A man who has been rimfired is liable to regard the person who rimfired him in much the same way he would regard a mule, always sort of half an ass and not to be trusted.
