Dach - DACH is like a German group chat with Austria and Switzerlan

DACH is like a German group chat with Austria and Switzerland. It's also a fancy way of saying 'we all speak German, but we all hate each other.'

My boss added DACH to the company logo. Now we all look like we’re in a German group chat.

I'm from DACH. That means I'm from Germany, Austria, and Switzerland. Also, I hate all of them.

Why is DACH on my LinkedIn? I didn’t sign up for a German-speaking hate group.
