Note 47 — THE HISTORY OF SLANG, OR THE VULGAR LANGUAGE OF FAST LIFE.
Reading edition

Horace Walpole quotes a party nickname of February, 1742, as a Slang word of the day:—“The Tories declare against any further prosecution, if Tories there are, for now one hears of nothing but the BROAD-BOTTOM; it is the reigning Cant word, and means the taking all parties and people, indifferently, into the ministry.” Thus BROAD-BOTTOM in those days was Slang for coalition.
