running black 

Stems from Running back, the position in football. Same concept as lineblacker but with a different position. The black running back's talents are equal to those of an ideal black man.

1. Coach Whitfield only plays black kids, he must love his running blacks.
2. That running black is as fast as Deion Branch.
