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.
