diddy bopping 

To walk using dance steps; in the Vietnam War it was used to mean walking carelessly whilst on patrol, to move through enemy territory without paying attention to your surroundings and thus putting the other members of the patrol at risk.
By extension to move or act without considering the effect on others.

Shadow Bumping 

When on an online car game your player is at a delay causing your car to hit other players when you didn't hit them or you hit a car that isn't there anymore.

Man, this game has so much shadow bumping. I keep hitting players!
