A decade spent partying on borrowed money, loudly, right before the bill arrived.

means The nickname for the 1920s, a decade of jazz, flappers, speakeasies, and economic exuberance in the US and parts of Europe before the 1929 crash ended the party.

from 'Roaring' here just means loud, wild, and full of energetic noise — jazz horns, dance floors, illegal gin joints — the opposite of quiet. The phrase caught on after the fact, in retrospect, as a shorthand for the decade's restless energy following the devastation of World War I and amid rapid cultural change: new music, new freedoms, new money, Prohibition pushing drinking underground into speakeasies. It's less a coinage with a single inventor and more a label that stuck because it captured something true — the sense of a society cutting loose, right up until the 1929 stock market crash turned 'roaring' retroactively ironic.
