Etymology: "Diddlywhackers" is American slang, and its origins are uncertain. It is generally treated as a playful, nonsensical formation built on the "diddly" and "whacker" pattern of informal English, where a rhythmic, bouncy sound carries the joke. Its earliest attestations appear in American English in the twentieth century, but the exact coinage and its first use cannot be pinned down with confidence. The "-y" ending and the repeated, bouncing sound follow a common pattern in childish and comic slang, as in "doodads," "thingamajig," and "whatchamacallit." Such words typically stand in for an object or body part that a speaker prefers not to name directly, or that is simply not worth naming precisely. The word "whacker" itself is an old, informal term for something large or striking, which adds to the comic, slapstick quality. Because the word is slang and its documentation is thin, there is no reliable story of a particular inventor or a notable first use. Its humor rests on sound and playfulness rather than on a traceable etymology.
