I'll stick with douche. In my mind, 'dick' doesn't qualify here.
I couldn't care less about the etymological roots of the word but I do agree with the other dissenters that it's an awful insult. Although whilst on the subject of Americani(z)ations, why the hell do they insist on sayin "I could care less" when we would say "couldn't care less". It makes no god-damned sense!
Anyhoo, good news I guess, though the whole Duke-N game subject has become a bit of a joke really.
