Bloody oath, mate.
i think the biggest issue people have with our slang is to them it makes no bloody sense take the use of the word bugger we use it if something goes wrong or we fuck something up most of the people i know from outside of the land down under see it as a filthy word meaning something else its sad that half if not most of out slang words we use everyday are seen that way but in true Aussie sprit i will say this Dilligaf
