Slang in the Army for having someone fuck your stuff up. Usually a threat to someone being insubordinate.
The term actually refers to tying someone's feet to the back of a
horse or vehicle and dragging them. Hence their skull would drag on the ground. But in practice it means to jack someone up, either through yelling at them, "smoking" them through push-ups, assigning
extra duty or generally being a
prick and giving them a difficult time.
