To bust someone's chops (nonliteral meaning) is to say or do something that interferes with someone's line of expertise or leadership in something. Chops = skills or simply a person's line of action, especially at the moment; and busting = to stop something or interfere with something.

Bust means "punch" and chops means "mouth", so "to bust someone's chops" literally means to hit them in the mouth, but most of the time it means to give (someone) a hard time.
