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.
Look at that Clown knob trying to pick a fight with that caravan salesman.
