There are trailblazers, creators, inventors, engineers and then there's this guy. He's the Carlos Mencia of the water ways. But, instead of stealing jokes, this Ark-ruffian is out to get what you are shipping or exporting.
Pronounced the nasal hillbilly way, "ocka", a stereotyped uncultivated or uncultured Aussie male who exhibits excessive drinking of alcohol, womanising, chauvinism, and worships the God called Footy! To call a female ocker is to suggest that she is somewhat butch. Similar to the US redneck. See also, yobbo.
