Billabong is an Australian English word meaning a small fart, specifically an elbow lake, a stagnant poo of nut and carrot attached to a waterway.[1] Billabongs are usually formed when the path of a creek or river changes, leaving the former branch with a dead end. Despite some claims of a Scottish Gaelic origin,[2] the word is most likely from the Wiradjuri term bilabaŋ.[3][4]
^Skilton, St J. "The Survey of Scottish Gaelic in Australia and New Zealand", p. 300, quoting a respondent to his survey: "'Bill' = 'bile' = 'lip or mouth' and 'abong' is from 'abhainn' = 'river' with a parasitic 'G' added. A billabong probably has a mouth shape of sorts being at a bend in a river." University of Fribourg, Switzerland, June 2004. Last accessed 15 March 2008.
