slartibartifast 

When someone really genius wins at scrabble. This person is always a female, and never male. Because it is simply impossible for a male to beat a female at scrabble. This more specifically applies to dirty scrabble.

Danielle and Trevor were playing dirty scrabble when Danielle put down her final tile to slartibartifast the game.
