City of (blank)

I was just asked what Dallas' label is --- you know The City of (blank). I've lived here all of my life and I honestly don't know the answer to that question, other than Dallas is often refered to as "Big D" which is terribly lame. There's got to be some old indentifier for this city that I've forgotten. In case there isn't, I made up my own. They include:

1. City of Hate
2. City That Killed Kennedy
3. City of Shitheads
4. City of the SUV
5. City of the low SAT score
