one chance
n.— «One chance is a robbery operation whereby we use vehicle to rob victims. We would pick unsuspecting passengers from the road, pretending to be going their way. But at the middle of the journey, we would stop and collect everything on the victims and drop them along the road.» —“How we dispossess our victims during ’one chance’ operations” Vanguard (Lagos, Nigeria) July 14, 2007.
