Neither fur, nor feather

by Lyudmila Golubeva - Russia
"Neither fur, nor feather" is always used as “good luck” before anything, such as a test, job interview, and other things.
The origin of this phrase comes from Russian hunters and is in fact, somewhat sarcastic/ironic. Feathers was slang for "birds" and "fur" meant animals, so the hunters were really told "Hope you don’t get any birds or animals, haha" to which they replied "To the devil," or rather, "The hell, I won’t."
