There's lots of 'birging' in this week's programme. For those not in the know - that's short for Basking In Reflected Glory and it's something football fans in particular do when they talk about their team's triumphs using the 'extended we'. Michael Bond author of 'Fans' talks to Michael about the words and language different fan groups have as a shared means of communication. Whether it's being a superfan of sport, film or music there are words and phrases that show you belong to a particular fandom.
