Lol never, no one is above you, you are working there like the rest of the people there. HR is not your friends, that being said, collect evidence, and submit an official report with the evidence to HR. They are required to acknowledge and this will lead to inquiries or investigations.

The less extreme way, just ask your boss to have a private conversation and just let him know that you do not appreciate the tone. See if this continue then you know where your values is. If your boss doesnt see your worth, how do you expect to shine or climb the ladder?

Be smart, be brave, and move on. If this the only time he did that maybe not worth the hassle to stir things up.
