Part of it is annoyance with myself, since I've always had an improbably extensive vocabulary, and I also have quite a few Australian friends, and I should have known "quantong" - except I'd never heard of it before. (I didn't eat very much fruit when I was in Australia - I was much more interested in Tim Tams and chocolate-covered candied ginger, and, yes, I did try Vegemite.)

You might be interested in a vocabulary game (http://www.freerice.com) that also accomplishes something useful, namely donating rice to the United Nations World Food Program.
