This meaning is not covered by the article. Perhaps also a mentioning of the expressions "rotten to the core" or "rotten on the inside" would be appropriate? I have no clue of the correct way to add them myself, but hopefully someone does!--22.214.171.124 06:26, 22 April 2009 (UTC)
Could rotten be related to the German word for to redden?
