My m-i-l (who has admonished me for saying "Darn!") uses an expression when she is really riled up ..... Horsefeathers!
It always scares me til she finishes the word.
My mom says "scheise" a lot.........when we were growing up she'd say "scheisekopf"......we thought we knew what it meant but weren't quite sure....
We were right.:)
