You've got no business here!

[Isotope]

Hi! Does anybody know what this expression means:

"You've got no business here!"

Is this another way of saying "Go away" or "Leave me alone"?

Thanks!

In simple terms it can mean "go away", but usually in the context of "what's going on here is no concern of yours", "you have no right to try and get involved in this".

It also, to me, implies a possible prior confrontation between the two people. If a stranger is where he doesn't belong, you would probably say somethings like "What are you doing here?" or "This is restricted property" or something like that. After all, if he's a stranger, you don't know what his "business" (in this context, purpose/motive/intent) is, and whether it actually does make sense for him to be there.
