get above (oneself)
To act in a conceited manner. Primarily heard in UK. Geez, you've gotten above yourself these days—the rest of us have opinions worth hearing too, you know!
1. To come to a position over or on top of something: I finally got above the wave and gasped for air.
2. To assume a superior attitude toward something so that one is no longer concerned with its problems and no longer worrying about it: Once you get above all this bickering, the answer should become clear.
