Either a corruption of brother, a modification of bud, or a borrowing from Pennsylvania German Bub or Southern German Bub (as was spoken in various communities in America before the early 20th century), ultimately thought to be derived from Proto-Germanic *bō- (“close [male] relation”) and thus cognate to English boy and babe.
