In the hood I'm a king, King Arthur to the people
Except he got his on a Chariot, I got mine in a Regal
King Arthur was the leader of Britain in the late 5th and early 6th centuries.
Jeezy likens himself to be like Arthur in his kingdom of hometown Atlanta, Georgia. They however have much different rides, as Arthur rode a chariot and Jeezy is riding in his Buick Regal. The use of regal, which means something fit for royalty, also continues the references to kings in these lines.
