hangover

1. (figurative) An unpleasant relic left from prior events.Examples: "The one hangover from high school that colored part of my college career was the social requirement of having a boyfriend."; "While they deny the logic of history and geography, neither Gibraltar nor the Falklands will ever be truly "safe". One day these hangovers will somehow merge into their hinterlands and cease to be grit in the shoe of international relations. This day will be hastened if world governments take action to end tax havens."figuratively

2. (historical) A sleeping arrangement, usually in homeless shelters, over a rope.Examples: "At the Twopenny Hangover, the lodgers sit in a row on a bench; there is a rope in front of them, and they lean on this as though leaning over a fence.
