streetwise
Having intelligence, wisdom, and shrewdness in the ways of the real world, especially life in a city (i.e. "the streets"). You've got to be streetwise to make it in this city, otherwise it'll chew you up and spit you out. I was pretty pampered growing up, but living on my own in New York City for four years made me streetwise.
