„kuff d’Schmull“: Shut up

“Jéinesch” is a dialect that was spoken in Luxembourg by the traveling merchants long ago, but now is almost extinct. Many words and phrases have been adopted from “Jéinesch” into Luxembourgish, such as “Moss” for an attractive girl or “Klont” for a prostitute. “Kuff d’Schmull”, a rude expression to tell someone to “shut up”, is used regularly by Luxembourgers today.
