Originally an acronym standing for 'Bloody Invalidity Fund', the terminology 'bif' fell into common use through the UK
police force and amongst traffic wardens for defining those members of the public who have
blue badge entitlement. The word has never been officially recognised and is often discouraged by managers in these politically correct times, however there are very few
police, traffic wardens or civil enforcement officers who are unaware of the word and its meaning. Often given the misspelling of
biff by those who use the word but are unaware of its original acronym.
