"Dallitude" (somewhat less frequently spelled “Dallatude") is a “Dallas attitude.” It has been described as the display of snobbery and/or elitism of a resident from Dallas, TX.
It's believed the term “Dallitude” was first found on a gay newsgroup posting from 1999; the term possibly originated in Dallas' gay community.
Today, Dallitude is more likely to refer to anyone from the city of Dallas displaying a "superior" attitude.
Example A: Down-talking the way others are dressed in a Dallas nightclub. "Can you believe her shoes?" This is display of Dallitude.
Example B: Driving a leased BMW on a $30k/year salary. This could be considered display of Dallitude.
Example C: A Dallas resident trash-talking other Texas cities while failing to acknowledge Dallas has just as many or more problems. Such as saying "Houston is polluted and crime-ridden!" In reality, Dallas ranks just a few places behind Houston on air pollution, and ranks higher than Houston on crime. This is Dallitude.
