A 'wogan' is a wog that has migrated from Europe to Australia, assimilated so well that they have rejected the style and class usually identified with Europe and veered towards becoming a bogan. They have absolutely no fashion sense; a day out involves going to the Rugby League, drinking copious amountes of alcohol, being loud and obnoxious and spending time working on their hotted up cars listening to Jimmy Barnes.
Wogan is the term used for people, often of Greek, Italian or similar descent, who are obsessed with crappy cars and dress in brands like Adidas, Eminem, Holden or Fubu, often decked out in bling. One celebrity example of a Wogan is Ali G. Likely to be heard saying things such as 'Fully Sick Moite!!'
Person 2: Yuck, what wogans.
"Fuck me, he was packin a wogan"
