black spot
n.— «A black spot is an acronym for any place or a particular area where bags, handsets or other handy valuables are often snatched by pickpockets who have studied such areas and knew quite well that a large number of people come to the area to transact business, which makes it easy for them to spot and identify their victims.» —“Sorry state of Apapa Ports” by Dele Aderibigbe Nigerian Tribune (Ibadan, Nigeria) May 2, 2007.
