Slightly odd question, and rather a long shot.
My grandfather had the army-aquired nickname of Busty, apparently referring to his size. Family legend records this as a Hindi nickname, but I can't find a Hindi word that matches, and he's long dead so unable to provide clues.
He was stationed in rather a lot of places but possible sources are Arabic, Nepalese, Marathi.
Anyone care to take a guess where it might have come from?
