Example B: Trash-talking about Houston (i.e. it is all concrete, has no culture and no positive attributes). This is display of Austitude. In reality Houston has forests of tall pine trees Austin does not, world-class arts/culture Austin does not, and a great restaurant scene Austin does not. (Dallas also has superior culture to Austin).
Example C: Saying Austin is so unique and has many things other Texas cities do not. In reality, Austin has many things borrowed from other cities such as chain restaurants, architecture, even the Art Car Parade (which has been going on in Houston for much longer). This is display of Austitude.
