mario kart rage

The rage that is induced by playing Mario Kart (especially on N64) even when the player does not become visibly angered by other video games.

Greg: Fuck! NO!!! How did you fall down there?! I pressed the button!
Don: Dude, it's just Mario Kart. Calm down.
Greg: You don't understand. RRGGH!
Don: Everytime we play you let your Mario Kart rage take over.
