Is this right?

No, it doesn't make much sense to me.
How can one obey a bag?!

pritesh prit He’s not obedient to the bag of bones.

It might be better to master ordinary, literal, everyday English first and save the slang, metaphoric devices, and poetic language for later. Just saying.

Thanks for your answers.

If "bag of bones" refers to a gaunt person, then this would be okay in certain situations. Gaunt people are often referred to as "a bag of bones." For example:

The headmaster was a gaunt, strict, and humorless person, who was often called "the bag of bones" by students.

Student A: "Everybody's intimidated by the headmaster, Mr. ___ , and they obey his every whim."

AnonymousGaunt people are often referred to as "a bag of bones."

Hence my reference to metaphor.
