How to self manage around a bully or a person who handles aggressive tactics .

While I like certain oranges, jumpers are not a good look on me… I want to grab this guy and shake him! He is aggressive and intimidates and pushes people to get his way and generally does. I have had multiple exchanges with him (which seem like sport to him) but I am depleted and don’t, can’t anymore. He says I have disrespected him because I have said boundaries and called him out (in private) on them but now I am being “punished” and I want to handle this the evolved way. I want to “leave happy” if that’s what needs to happen or smartly, not like this. Please help me navigate this.
