It's easy to forget how international this site is and assume that everyone is familiar with Australian sayings
"bear my backside in Bourke Street" is a saying/phrase that goes back into the 1800's it's used all the time when someone doesn't believe something will happen.
If you search Google you will find many references, including this from our State Parliament on page 154 when debating finance:
http://www.parliament.vic.gov.au/do...Council Extract 23 March 2005 from Book 2.pdf
"What are interesting are some of the comments that
have come out of that. The shadow minister made some
comment that we were ripping $160 million out of
WorkCover. That is something I am happy to engage
on with him in a discussion at a later time. One thing I
am interested is this, and I refer the house to the Age
article by Lawrence Money on 7 March 2004, where he
said that the shadow minister ? and
I need to be
careful how I say this in the house so as not to upset
sensitivities ? would bare his gluteus in Bourke Street.
He would bare his backside in Bourke Street if we ran
on the profit."
There is another saying that is equally as popular and I am so very glad I did not use it - "walk Bourke Street backwards bearing my ass"
