I'm a Coordinator at an English course in a small city in Brazil, and one of the teachers called me "boss" today. However, I don't appreciate being called that, therefore I'd like to tell him not to do so. I'd rather do it in a colloquial way, though. So, how can I say it?
Hey, man. There's no need for this "boss" thing, you know.
Come on, man. Don't "boss" me. There's no need for that.
Could you guys give me other examples of how you would say it with your own words?! I have no idea how to say that colloquially.
