"Nuts." Battle of the Bulge. Response of surrounded American General Anthony McAuliffe to the German suggestion that he surrender. It may be a euphemism.
"Nuts" is correct Faldage. In July 1976 I interviewed a WWII vet - Robert Simard - who was there with McAuliffe when he uttered the memorable quote and Simard confirmed the quote.
No euphemism - wait - let me say that Simard said "Nuts" was indeed the word McAuliff used. What the good General had in his mind only he knows!

Ole ! - any bullfight
Bravo!
