Vehicle Borne Improvised Explosive Device - basically a car bomb used by the hajis in Iraq because they are cowardly pussies and know they don't stand a chance in a face to face battle. They rig up charges to old artillery rounds (122mm?), C4, or whatever. They can make it blow by using a cell phone to blow it. Or it can be command detonated but they are usually to big of a pussy to do that, too.
