Although many people believe Brexit is a high-fibre cereal that encourages regular motions, it is in fact, a recently coined word intended to describe the situation in which Britain leaves the European Union.
Should Britain decide to remain within the EU, this will be known, particularly to people from Essex, as Brinnit.
In a similar vein, Bridle is the approved expression for doing nothing, Bramble the authorised description for walking slowly to the voting station and Brian the accepted term should the majority of votes be cast by snails.
