“Bigger than Dallas” (“Bigger ‘n Dallas”)

Dallas is big. Houston, however, is the most populous city in Texas. Dallas has long been nicknamed “Big D.”

The phrase “bigger than Dallas” (“bigger ‘n Dallas”)—meaning something that is very big—has been popular since at least the 1960s.

“I’ve never been to any place bigger than Dallas,” said Chief Hefley. “You all ought to see Dallas at the time of the state fair. It’s a mighty lively town. The most beneficent work of providence, I think, was putting the Indian territory between Texas and Kansas. It was necessary to have something there to prevent things. The settlement of the territory may be the cause of making a sort of tapering off place from each state, so that the people will be able to become used to each other by degrees.”
