Other forms: klatsches
A klatsch is a gossipy get-together. Your grandparents might tell you about their weekly coffee klatsch at a local diner, where they chat with friends over cups of decaf.
The German Klatsch means "gossip" and is thought to be imitative, based on the chattering sound of gossiping voices. Any casual gathering that's focused on gossiping or catching up on the latest news can be described as a klatsch or a klatch. These events are closely associated with drinking coffee — and there's a word in German for that, too: kaffeeklatsch.
