A katzenjammer is an unpleasantly loud, confused, and dissonant sound. A katzenjammer next door might keep you awake all night and make you cranky all the next day.

The noun katzenjammer, while considered somewhat outdated today, has at times been used colloquially to mean various kinds of unpleasant sensations, from general confusion to depression to noisy uproar to a bad, dull headache. The word means "cat's wail" in German, from katze, "cat," and jammer, "distress" or "wailing."
