|1.||Shitter than Lightning|
When something diabolical has happened, in real life, this term helps fellow Mario Kart players know the seriousness of the situation.
Something worse than "shitter than lava", can only happen after Shitter than Lava has struck once. Shitter than Lightning can strike twice in the same place.
Mate, your car crash was shitter than lava. But the way the insurance dealt with it - was shitter than lightning.
