Definition: 1. A golf ball specifically manufactured for use on a driving range, or used balls that in use at a driving range. Golf balls made for driving ranges feature very hard covers so they won't be easily cut or damaged. Range balls often have a black or red stripe going around them and so are easily identified.
2. A derogatory reference to a golf ball that is not performing as hoped (usually at the fault of the person hitting it). One partner to another, "That shot was ugly. Are you using a range ball?"
