The Coolest Three Word Conversation Ever

I went down to the shipyard today, with every other engineer from my group in tow, to check out a giant test fixture that had just returned from shock testing in Virginia. It was a great trip. On the return to our building, we walked by a few conex boxes (the size of a mobile home) that some crews were working out of. One had a painter (judging by his coveralls) sitting in the doorway in a folding chair, soaking up the gorgeous sunshine. Being the point man (or mother goose for the goslings that followed my steps to avoid getting lost or into trouble), I threw a quick wave and a disarming smile to the gentleman, a dignified, middle-aged black man. This is a quick signal that "We engineers are frightened and confused by the primitive ways of the shipyard, and are only moving through peacefully in search of air conditioned offices with coffee makers.". The painter, obviously gathering my meaning, nodded behind his reflective sunglasses and simply said with a deliberate, basso profundo:
"What it is."
Seriously. I haven't heard that phrase uttered un-ironically in decades. Not only that, it perfectly summed up this individual's all-out lounging and laissez-faire attitude toward our band of interlopers in his world. No further conversation was helpful, desired, or necessary. Indeed.
