[["Willy nilly" - the slightly corrupt transliteration of the Latin "volens nolens".]]

It may come from that same Latin phrase, but I thought "willy nilly" was a slight corruption (as in mumbling) of the phrase "Will ye, nil ye," as was used in Shakespeare's "The Taming Of The Shrew" (meaning "whether you like it or not").
