To be sanctimonious, pretentious and conceited about how unpretentious and un-conceited one is.
I went to a party. They called it a barn dance but there was no barn. It had some bands playing, but the only people watching them were in the other bands. Everyone was talking about how they never go north of Town Lake anymore. It was very Austintatious.
marked by or fond of sometimes pretentious display that is unique only to Austin, TX.
Our austintatious day included a swim at Barton Springs Pool.
