A high school in Chester, VA. All the locals are rednecks and they have a specialty center for the arts that includes music, dance, theatre, art, and film. They all think that they’re quirky because they own doc martens. Thomas Dale has the best principal in all of Chesterfield County, and he loves the students with all his heart.
“Did you hear about the ThomasDale High School football team?”
Dale Earnhardt (1951-2001, NASCAR driver) was for many an example of how a common man can achieve great things if one makes enough effort, and takes the chance whenever possible.
As so, "Do it for Dale" means something like "He'll be proud of you, so do it."
Our redneck savior. He crashed for our sins, and on the third lap, he rose again, and ascended into heaven, where he rideth shotgun for our Lord, the Almighty God.
