euphemistically speaking
Some of the best euphemisms are lauded as "doublespeak", dear wwh. My favourite: Remember when the American Embassy in Teheran was beseiged by murderous mobs and President Carter dispatched a fleet of helicopters from the desert to rescue the Americans trapped there. The helicopters crashed into one another on take-off and the mission ended in a self-propelled sandstorm. Afterwards, President Carter described the rescue mission as an "incomplete success".
