Get out of my space, Get Out of my bubble. To ask a person not to crowd you or to move from a place you were sitting or at prior to the persons encroachment. Get Off My Lawn Means Move Away!!
A person is in your seat "Hey Get Off My Lawn" A person is too close in a conversation "Dude Get off My Lawn"
