A glancing blow is a type of impact that occurs when two objects make contact at an angle, rather than head-on. The term can be used to describe physical collisions, such as when two cars sideswipe each other, or when a person swipes something from another person. It can also be used to describe a more subtle interaction, such as when someone snicks something away from another person. In all cases, the contact is not direct, but rather at an angle.
