“If Kate Winslet had been the Duff, Leonardo DiCaprio wouldn't have been after her in Titanic and that could have saved all of us a lot of tears.”

“I was the Duff. And that was a good thing. Because anyone who didn't feel like the Duff must not have friends. Every girl feels unattractive sometimes. Why had it taken me so long to figure that out? Why had I been stressing over that dumb word for so long when it was so simple? I should be proud to be the Duff. Proud to have great friends who, in their minds, were my Duffs.”

“En la película, la pobre Keira Knightley tiene que pasar por toda esa maldita tragedia con James McAvoy, pero si Keira no hubiera sido atractiva, el nunca se habría fijado en ella y no le habría roto el corazón. Al fin y al cabo todos sabemos eso de que “es mejor haber amado y perdido...”, todo ese rollo es una mierda.Esta teoría se aplica a un montón de películas. Piensa en ello. Si Kate winslet hubiese sido la “Duff”, Leonardo DiCaprio no se habría enamorado de ella en Titanic y nosotros nos habríamos ahorrado un montón de lágrimas. Si Nicole Kidman hubiese sido fea en ColdMountain, no tendría que haberse preocupado por Jude Law cuando se fue a la guerra. La lista es interminable.”

“"...we’re all fucking Duffs.” (Designated Ugly Fat Friend)“I’m not the Duff,” Wesley said confidently.“That’s because you don’t have friends.” (Bianca)“Oh. Right.””

“I shook my head. "Don’t bother making excuses," I said. "Don’t waste your time because, the fact is, I am the Duff. But so is everyone else in the world. We’re all fucking Duffs." "I’m not the Duff," Wesley said confidently. "That’s because you don’t have friends." "Oh. Right.”

“Calling Vikki a slut or a whore was just like calling somebody the Duff. It was insulting and hurtful, and it was one of those titles that just fed off the inner fear every girl must have from time to time. Slut, bitch, prude, tease, ditz. They were all the same. Every girl felt like one of these sexist labels described her at some point.”

“I meant that a decent guy - a smart guy - wouldn't have let something like sex ruin a good thing.”
