Is a variation of the traditional aussie term Bogan, which has become Bogie then Wogie. A wogie is like an uber bogan, wogies drink heaps of bundaberg rum, cheap and nasty aussie beer like Tooheys new and enjoy wearing singlets, saying "aaaah yeeeeh" alot and spend their weekends doing things like Mud Racing and the like.
What a wogie, did you see the state of his mullet. That was proper wogie behaviour, the way he has car parts all over his garden. Look at the photos of this remote australian town, thats proper wogieville that is.
