A racial slur I'm wondering about.

[IndeX]

I was watching one of my favorite movies recently, called "The Castle." If you haven't watched it, it's a wonderful piece of Australian film and humor.

Anyway, there is a character in there named Farouk, who I believe to be either Yugoslavian, or maybe Russian, I honestly don't know. He is talking to the main character and tells him"I weel pay now, een cash." for something - but the main character tells him:

"Don't worry 'bout it yet, we don't have to pay the bill until later. What is it with wogs and cash!?"

Now the term "wog" is obviously a racial slur like "wop" or "spick" or what have you, but what ethnicity does it refer to? Does anyone know? I'm just curious - I'd never heard the word until I saw this film, and I hadn't thought of the word until last night when I watched it again.

Any help would be appreciated.

EDIT: btw - here's a picture of the actor, Costas Kilas. He's the one on the far LEFT.

Urban Dictionary is a good place to look up slang, insulting or otherwise.

Wog:
(UK) a dark-skinned national of a Colonial British colony. It is sometimes said in jest that "the wogs begin at Calais." Used frequently in Lawrence of Arabia to describe locals, "bloody wogs". The term, once very offensive, has been appropriated by second-generation ethnic youth and is used humorously or with pride, as in "wog culture" and the successful comedy show Wogs Out of Work. The origin of this term is unclear. Possibly derived from Golliwog. Some people claim that Wog is an acronym for 'Western Oriental Gentleman' or 'Wily Oriental Gentleman', but this is almost certainly false.
(AUS) an aborigine, or Mediterranean-European (especially Greek or Italian) person (or any foreigner).
