Why are the Charlton FC called The Addicks?

The Addicks

Something to do with the old charlton team having fish and chips after the game with the opposition and because of their cockney accent it sounded like they said addick instead of haddock, so the nickname the addicks has stuck

The nickname was born during the club's early days in the 1900's when Charlton were sponsored by a fishmonger called Arthur Bryan. After each match, Bryan would give each side a fish supper, and when Charlton won they would be given haddock, or 'addock' in the vernacular of southeast London.
