bad

Etymology 1

From Middle English bad, badde (“wicked, evil, depraved”), of uncertain origin. Perhaps a shortening of Old English bæddel (“hermaphrodite”) (for loss of -el compare Middle English muche from Old English myċel, and Middle English wenche from Old English wenċel), or at least related to it and/or to bǣ̆dan (“to defile”), compare Old High German pad (“hermaphrodite”). Alternatively, perhaps a loan from Old Norse into Middle English, compare Norwegian bad (“effort, trouble, fear”, neuter noun), East Danish bad (“damage, destruction, fight”, neuter noun), from the Proto-Germanic noun *badą, whence also Proto-Germanic *badōną (“to frighten”), Old Saxon undarbadōn (“to frighten”), Norwegian Nynorsk bada (“to weigh down, press”).

verb

1. (Britain, dialect, transitive) To shell (a walnut).
   A curious specimen of Gloucestershire dialect came out in an assault case heard by the Gloucester court magistrates on Saturday. One of the witnesses, speaking of what a girl was doing at the time the assault took place, said she was ‘badding’ walnuts in a pigstye. The word is peculiarly provincial: to ‘bad’ walnuts is to strip away the husk. The walnut, too, is often called a ‘bannut,’ and hence the old Gloucestershire phrase, ‘Come an’ bad the bannuts.’ 1876, The Gloucester Journal, Oct. 7, 1876, reported in A. Gregory, “Gloucestershire Dialect,” Notes and Queries, 5th ser., 6, 148 (1876‑10‑28): 346
