Cabbie Cake
The wad of money a cab driver gathers in any given shift. Usually comprised of smaller denominations.
That veteran Hack sure knows how to scoop up the Cabbie Cake. He can sure put the heat on the street and when he displays his Cabbie cake it is taken as a warning to others that this is his zone. He owns it in style as he hoists the Cabbie cake high in the air. An intimidating gesture clearly intended to strike uneasiness in others.
