In reply to:

I was reminded today by a wwftd correspondent of the following from Men at Work:

Do you come from a land down under?
Where rivers flow and men chunder?
Can you hear it, can you hear the thunder?
You better run, you better take cover.

conventional wisdom here in the U.S. is that they meant 'to vomit'; perhaps conventional wisdom is wrong?

Not too sure about "where rivers flow". No, damn it, that wasn't what I heard, either on the record or at their concert. Can't remember exactly what it was, but I believe the word "beer" came into it!

OZ and Godzone share a lot of this kind of slang. "Chunder" is a relatively mild and unexpressive term for vomiting in the wider context of terms available. Others, off the top of my head, include:

"To sell out"
"To have a conversation with the Big White Telephone"
"Peas and Carrots" (this one should be self-evident to most ...)
"Throw up"
"Technicolor Yawn"

And the list goes on, and on, and on, and on ....
