In Australia, one of the definitions of the term 'wog' is what other australians call europeans and now lebonese.
It used to be a racist word a while ago, created for the italians, greeks and maltese when they all came rushing in during the late 60's and most of the 70's.
Now, it's used as a replacement for the word european (the english and french are not considered wog though), it's socialy acceptable these days; can depend how you say it (examples below).
example one; racist.
person: oh my gosh shes such a greasy wog! she needs to go back to her own country. wogs these days.
example two; non racist
person1: hey, are you wog?
wog: ahah yeah *continues scoffing pasta down*
person2: ahah your so wog, love it.
