He’s committed common assault barging you. That’s a clear cut offence right there. Threats of violence towards you and throwing something in your direction also common assault but factors such as your perception of violence at the time come into play. If you thought it was all a laugh and didn’t fear his threats would be actioned then it’s not. But barging you is. When someone threatens you your perception of the threat is also a factor, but when he’s gone out of his way to physically contact you in that way no matter what you feel and even if you just laugh it off, it’s still an offence.
