A return response to an Aussie mate (male) usually over a few beers who says something so outrageous that “fair dinkum” just doesn’t cut it.
Mate at pub: Went fishing, fell in the water, got attached by a shark, managed to get out of the water fairly unscathed and scored a root on the walk back to the Ute.
A vehicle that a dindu had "borrowed" and now drives.
The more advanced the dindumobile, the more a dindu nuffin has to increase its skill in order to operate such vehicle. Sometimes this is a huge deterrent since dindus naturally have an average IQ of 65.
Last week, Tyrone "received" his new dindumobile - a shiny new bike! Now it's muddy and almost broken, but that's okay with Tyrone because there are many bikes in this world and he is just one dindu nuffin.

I recently went to the cops to report my old Honda Civic was stolen. When the cops arrived at the dindu's house it said "SHIEEEEETTTTT I DINDU NUFFIN DIS MUH DINDUMOBILE WE WUZ KANGZ U RASIS WHITE COP CRACKAH I DINDU IT". Fortunately the dindu wasn't in my Honda Civic when he said that, otherwise my car would've been full of bullet holes.
Usually a term used to confirm the truth of a statement.
The origins of this term are disputed but a plausible one is that it came from the Victorian Goldfields where Chinese workers used the term Ding kum so confirm a deal that is honest and true.
