Animals also abandon or eat their own offspring. Dogs will mount and/or mark (i.e., urinate on) other dogs to communicate dominance. But these are generally not considered by humans to be a viable form of communication or behavior.

In fact, I am pretty sure there are human laws against "mounting" another person in a display of dominance without consent... Or perhaps society has blown the whole "rape" thing out of proportion, too?

Also, I agree with what was said above, that such an incident should be taken very seriously. He has absolutely no right to hit you.
