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!

I have Bumpanitus, and I've deranked from immortal 3 to diamond 2.
