That’s funny! Do you say “an Irish goodbye” in English when someone leaves without saying goodbye? In German, we say “einen polnischen Abgang machen”, which literally means “to make a Polish exit.” (Apologies to my Polish friends!)

Edit:

Just learned international Names for it:

Germany: Polnischer Abgang (Polish exit)

United States & Ireland: Irish goodbye

United Kingdom: French exit

France: filer à l'anglaise (to leave the English way)

Poland: wyjść po angielsku (to leave the English way)
