\ KAT-suhn-jam-er \ , noun;
1.The discomfort and illness experienced as the aftereffects of excessive drinking; hangover.
2.Uneasiness; anguish; distress.
I love the sound of this word. Though I do feel like if I ever desired to use it, it wouldn’t go over well. “Are you experiencing a katzenjammer?” The hungover one would not think this was funny or educational or enlightening, but annoying and loud.
