Reminds of how Father Mulcahy's original nickname of Dago Red was dropped because even though it's the name of the sacramental wine he got drunk from in the novel and movie, apparently "Dago" is a insulting word for an Italian (kind of like how "cracker" is an insulting word for a white man, or the n-word being an insult for a black man).
Now as far as I'm concerned, "spunky" describes someone has being eager, and full of energy, so I'm interested in knowing what it means to people in Europe than they find it offensive.
