chunder down under 

An Aussie tradition, in which someone vomits in the dunny of a local pub, having spent a morning at Bunnings, consumed 3-4 Aussie tacos , drunk extensive amounts of cheap tap beer and prior to visiting the local rips (strip club).

Mate 1: Where’s James, mate?
Mate 2: Strewth mate, he’s in the fucken dunny having a chunder down under.
Mate 1: Well tell him to hurry up, we’re gonna miss happy hour at Kittens.

Chunder from Down Under 

The act of violently vomiting to the point that it causes one to evacuate their bowels at the same time from all of the straining.

To add insult to injury, as I retched into the toilet, a felt a release in my bowels and knew it was the chunder from down under.

The Chunder From Down Under

When you release an absolutely monstrous spillage from your anus, rivaling that of the Niagara itself.

Down Under Chunder Wonder 

Vomiting with enough force while going down on a girl to finish her off.

After a big night on the drinks I was going down on the missus and started to feel the room spin. I knew she was close so I persisted but as she was about to cum I power chucked in her spasm-chasm and the force from my puke finished her off. That night the Down Under Chunder Wonder was born.
