Mario Kart pissed

1. A notably sever and predictable reaction to various exchanges and interactions between gamers and the popular Nintendo 64 game ‘Mario Kart'; where cursing, racial slurs and ‘chucking’ of controllers are often and uncontrollably used as the body’s natural, emergency means to alleviate stress buildup as well as the swelling of blood vessels in the neck/face/head. Side effects can include loss of friendships, bleeding from the eyes, broken toes and in severe cases, ‘sharting’.

2. A similar level of rage caused by any situation.
