The phrase describes a common type of puzzle entry. Specifically, it refers to the solution one might find when solving a crossword puzzle where the clue references a retired basketball player with the name Ming. The answer is typically a variation of that name, often written in a way that fits the constraints of the grid.
Such clues are useful to crossword constructors for several reasons. Names, especially well-known ones, provide readily accessible and verifiable fill. Additionally, using a former athlete adds a layer of general knowledge testing to the puzzle. The specificity ensures a unique and challenging, but ultimately solvable, word puzzle entry. Their inclusion helps create a diverse and engaging experience for solvers.
