A Gibbo
A thick, uneducated Aussie who lives in the western suburbs, works as a labourer, and thinks he's the king of the world. He's usually called a bogan or a yobbo by smarter people.
''He's a gibbo, living in the western suburbs like a chump.'''
''That gibbo thinks he's the king of the world.'''
''He's a gibbo, and he works like a chump.'''
