"Do you live in Brighton?" "No, I live in Hove actually."
Hove-Actually is the quieter gentrified end of Brighton & Hove, the seaside town South of London, that is otherwise known as 'Brighton'. The thing is, Brighton's bohemian and alternative image doesn't suit most inhabitants of Hove, so when you ask them if they're from Brighton then tell you that the live in 'Hove, Actually1'.
1 Said in a sufficently plummy accent for 'actually' to rhyme with the 'le' in 'leg'.
