Also British slang for a run-down area of a city (often a particular street) known to be frequented by street drug dealers.

Usually a bad place to score, for the following reasons:

  • Everybody knows about it, hence the Police are usually around.
  • Lots of dumb kids go down there and get sold pieces of wood or Oxo cubes. Duh.
  • You are likely to get ripped off or mugged due to the inherent dodgyness of street dealers.
  • You will be highly unpopular with the locals, who dislike the neighbourhood being used like this and are annoyed at being constantly asked for drugs.
Cities that have a Frontline that I am aware of; Bristol, Derby, Manchester, Birmingham, San Francisco, and several parts of London.
