It's assault and battery. Tortious and criminal, in English and American common law for centuries.
The inability of the British left to distinguish between words and the use of force is astonishing.
"[T]hough no great bodily pain is suffered by a blow on the palm of the hand, or the skirt of the coat...these are clearly within the legal definition of Assault and Battery."

"The least touching of another's person willfully, or in anger, is a battery; for the law cannot draw the line between different degrees of violence, and therefore totally prohibits the first and lowest stage of it: every man's person being sacred."
