distress, depression, or confusion resembling that caused by a hangover; or, a discordant clamor
"Tired and hungry, he found the frenzy of the carnival less thrill than katzenjammer."
About the Word:
The German Katzen means "cats" and Jammer means "distress"; the early German sense of katzenjammer referred to a hangover.
The "discordant clamor" sense of Katzenjammer became popular thanks to the cartoon strip The Katzenjammer Kids, which first appeared in 1897 and featured two mischievous boys and the victims of their antics.
