Disgraceful means so bad that it brings shame — bad, embarrassing, or not acceptable. We say it about what people do, not usually about a clumsy body: leaving a hurt animal in the road, cheating, being cruel, treating someone badly. It is a strong, judging word. Parents, teachers, and newspapers use it when they want you to feel the shame, not only that something was “wrong.” It can sound a little stiff, but people still say it when they are angry. You can also use it about a state of things (“the room was in a disgraceful mess”), meaning it is so bad it feels like a shame, not only untidy. Though actually, it is not the opposite of graceful. A person can move smoothly and still do something disgraceful. The word is about shame, not about how someone walks.
