day of doom

1. The end of the world; judgment day. Every year, another nut job comes on the air, talking about how we're coming close to the day of doom and that we must all repent our sins. The disgraceful way some people act these days makes me wonder if the day of doom is coming sooner than later. When we go to these tornado-ravaged neighborhoods to render aid, it feels and looks like the day of doom.

2. By extension, any moment characterized by catastrophe, disaster, or complete ruination. The day of doom in my life was the day my daughter was killed by a drunk driver. It was a day of doom on Wall Street, as the property bubble burst and the economy plummeted to historic lows. John F. Kennedy's assassination was a day of doom for our parents' generation.
