A "ding" is a small sound that's often loud and sharp. It can also mean hitting something gently.
When people talk about dings, they usually think of that little "ding" sound first. But sometimes they might use it to describe when an object collides with something else - for example, if your car gets a minor scratch after bumping into another vehicle on the road, you could say it got a ding. It's not as severe as a crash, but still noticeable.
Very minor damage, a small dent or chip.
To hit or strike.
