A derogatory term for Americans, originally a word play on "yank" rhyming with septic tank, shortened to "seppo". The term became popular among the British and the Australians around the time of WWII, when American soldiers were staged in both respective countries on the way to battle in Europe and Asia. At the time, the populations of both countries greatly resented that the Americans were able to seduce their woman with such ease. Not having much recourse, they lashed out the only way they could, creating silly derogatory terms.

A person from the Australian state of New South Wales; used as slang derogatory by Victorians and Queenslanders.

Explanation: The three eastern states of Australia are Queensland in the north, Victoria in the south, and New South Wales between them. They are colloquially seen as being Canada, Mexico and the USA respectively. Since seppo is a slang term for American (see above definitions), it becomes a slang term for a New South Welshman.
Victorian: The damn seppos won the 2005 AFL premiership.
