Demi-Sauce

A condition when your skill in a game unpredictably skyrockets with you having so much spicy sauce all of sudden but only for a short while. It can be for a week or a month but one day all that sauce will unpredictably disappear without warning. It may also temporarily return but will eventually vanish yet again creating an unescapable paradox of skill.

Person 1: "I thought Jim was good?"
Person 2: "Oh, Jim? He has the common condition of Demi-Sauce. He will probably never be consistently good at any game."
Person 1: "That poor thing."
