Finally I know what Chavs are!!
I'm not sure what the Aussie equivalent would be. The closest thing I can think of is Bogans - foul-mouthed, footy-watching, women-bashing, beer-swilling rev-heads, usually intensely homophobic, who are seen either having arguments over whether a Holden or a Ford is a superior car, or cruising around in one of these and shouting obscenities to drivers of the other. Also, they generally tend not to listen to hip-hop, instead favouring 80s heavy metal - the only thing I have in common with them (Metallica rock!!!). Great cartoon man, goood satire is so hard to come by these days.
