What would someone get charged with if they threatened to and then shaved off my eyebrows?

If someone threatens to shave off my eyebrows when I go to sleep against my consent, and then proceeds to shave them off, again against my consent, what would this person be charged with? I thought it might be both ault and battery, because I thought ault meant something that was premeditated or a threat to commit the action, and battery was the actual physical action against me, and you could say argue that it's bodily harm. Please, serious answers here. Thanks for the help!
