When a person sabotages you for doing better then them. Reference to the blue shell in Mario Cart that takes out the player in first.
Jeff from accounting was Blueshelling me from getting that promotion by telling the boss I slept with his wife.

Damn it. My opponent activated a blue shell and I blueshelled from first to eighth. How am I gonna be a pro at Mario Kart?!
