Heh, I still say "mafu" to mean tomato, because one of my big sisters used to say it as a toddler. I *still* think my mother is the greatest.

(Though my family can be unintelligible to outsiders; conversations like

-Where did I lost them, John?
-sur la table.
-oh right. Bainne, bitte.
-We have no klim, but there's mafu juice...

They make perfect sense to US. But it did confuse the hell out of Rob, first time my little sister came to stay.
