What's The Dutch Word For Moron?

Some maroons in the Netherlands think the world will end in 2012:

"You know, maybe it's really not that bad that the Netherlands will be destroyed," Petra Faile said. "I don't like it here anymore. Take immigration, for example. They keep letting people in. And then we have to build more houses, which makes the Netherlands even heavier. The country will sink even lower, which will make the flooding worse."

I thinks it's idioot or something like that, just as it was in English before the Normans screwed up our fine Anglo-Saxon tongue.
