Found in many countries round the world, the big club nonce (BCN) is a supporter of a 'big' sports team, usually, but not exclusively, a professional Football (soccer) club. The main characteristic of a BCN is that he or she thinks they are somehow superior to a supporter of a smaller team just by virtue of the fact they support a big club. This perceived superiority is not limited to football knowledge, and when called out about being BCN's they get as angry as actual nonces get when peadophile hunters catch them and film it live on Facebook, hence the use of the word nonce (which at one time was considered to be offensive but is now common place). The BCN is usually a glory hunter and often shunned by supporters of their own team.
BCN: what would you know about the 4-3-3 system, you support a league one side?
Other supporter: Mate pack it in you sound like a big club nonce.
Also:
BCN: We should be beating teams like......
Other supporters: Jesus mate you sound like a big club nonce.
Also:
BCN: Why would you spend your money supporting that rubbish
