A word (or phrase, sentence, etc.) is said to be king-graphable (KG) if each of its distinct letters can be placed on a square of an infinite chessboard such that the entire word or pharase can be spelled out by starting on the first letter and making only the moves of a chess king to get from letter to letter.
