Yes, it is a real word. No, it doesn't refer to an idiot. A "haboob" is the Arabic name for a dust storm and the word was being bandied about all over the news this week when a huge haboob hit Phoenix, Arizona on Tuesday. You can watch the incredible video which looks like something from an apocalyptic Hollywood thriller. In fact, it looks like the exact thing Tom Cruise is trying to out-run in the newly released MISSION IMPOSSIBLE trailer.
Anyway, here's the video of the Haboob Of The Week that hit Phoenix. Note that this is time lapse to that makes it look a bit scarier than it really is. But the dust apparently did get all over everything....it even set off a lot of smoke detectors in people's homes. Some think it was the large haboob to hit the city in a century.
