1)Noun: Pronounced Deee Bomb. D-Bomb is short for Drill Bomb. Drill bomb is a term used to define the actions of one marching on a football field or mat for Percussion or Colorguard groups. The actions of this one are usually careless, nonchalant, and disregardful of any instructions given to them by staff, or any other higher authority.
