You don't even need to get punched. In most jurisdictions simply placing someone else in a situation where they perceive an imminent threat of bodily harm from you, is enough to make out the offence of "assault". Certainly if he is uttering threats, that is a criminal offence as well. Not sure exactly what was meant by "hostile confrontation" but technically, crimes may have been committed already...

And be careful...
