The effects of hangovers have been hanging around for ages. The word itself, however, has only been fermenting since the late 19th century. Originally, hangover described someone or something that remained or simply survived, but it was later distilled into common use as a word for the effects of overconsumption of alcohol or drugs. These days, hangover can also suggest an emotional letdown or an undesirable prolongation of notes or sounds from a loudspeaker.
