Extravagant and infeasible promise made with vigorous enthusiasm, commitment and great charisma and precisely zero intention of implementation at any future date. Often abbreviated to its acronymic form "BS". Popularised by the British prime minister, Boris Johnson. A portmanteau word with origins in the archaic Russian word Borispav describing a confidence trickster's widening smile as his victim is duped.
