Popularized by League of Legends players, Mental Boom refers to the state in which your mind is taxed or exhausted to the point where your decision making becomes compromised, often directly caused by tilt or tilting circumstances. Players who are Mental Boomed often have very low desire to win, and have an often severely negatively affected performance. Some form of mental reset is needed to players experiencing Mental Boom.
