Etymologie
() Suggested as having an Australian aboriginal origin . If so, then it seems likely to come from binghi (elder brother) which appears in Aboriginal dialects, also seen as bung (elder brother), in Indonesian dialects, (see also R. M. W. Dixon, Australian Aboriginal Words'', Oxford University Press, 1990, ISBN 0-19-553099-3, page 165). Previously the word binghi was used widely in similar fashion to the present-day use of the term Negro for peoples of African ancestry, see titles from and also writings of (eg in Capricornia), for example. Whatever the origin, the term now spelled boong has taken on a particularly offensive slant, especially after spreading of a joke concerning the supposed etymology of the word, which in the joke is given as onomatopeiac, and due to a supposed practice of wanton disregard for road-safety of pedestrian Australian Aborigines.
