"Show them who's boss" is an idiom meaning to demonstrate superior power, authority, or skill to someone challenging you, proving you are in charge or the best, often through action, asserting control, or outperforming them. It's about establishing dominance, whether in a workplace by working smarter, in a new social situation by setting boundaries, or even with a pet by training it.
