A reference used by the supporters of Crystal Palace
FC to describe another set of South London supporters, the Charlton fan.
For years, the Charlton supporter (or Clown as they are commonly known) has tried to
bait and bully their way into a rivalry with their neighbour (who already have a deep and ancient rivalry with Millwall
FC and Brighton & Hove Albion
FC) but the worst insult anybody could think of on the Crystal Palace side was 'knob' as the Palace supporter really cant bring themselves to
hate them.
