Etymology: "Ditz" is a back-formation from "ditzy," meaning that speakers took the existing word "ditzy" and, by stripping off its ending, produced a new noun. Speakers rarely do this deliberately; the noun simply appears by analogy with pairs where a noun was formed first and an adjective grew from it. Here the process ran in reverse. "Ditzy" was already in use describing someone scatterbrained, and "ditz" emerged as a short, punchy label for such a person. The adjective "ditzy" is the older and more basic form in this pair, so the noun is best understood as a shortened, informal version of a descriptive term. The informal "-y" adjective ending is common in spoken American English, which is one reason this family of words sounds casual and chatty. The noun form carries the same sense of carelessness and distraction, now applied directly to a person rather than to a quality of behaviour.
