yikes, they are flashing their mobs! (or mobbing their flashes?)

Baghdad Flash Mob!

what do people actually do in those flash mobs, and will they all be attending wearing same color t-shirts, because if not baghdad these days looks like one big flash mob. More worringly in this some devilsh way to get bloggers and internet geeks to congregate in one place so that the freaky jihadis can get ris of them in one single go? is this the first Flash Mob suicide attack?
I need to go get water I feel a bit light headed and paranoid. It might be the fumes from our crap generator.
