look up any word, like bae:
Bad through-and-through. Those who are bad to the bone are born that way. They make rich women beg and good women steal. Everyone fears those who are bad to the bone.

'Bad to the Bone' is also a famous 1980s blues rock single.
She could tell right away, I was bad to the bone.

Have you ever met that Mariusz Pudzianowski? He's bad to the bone.
