**edited with a warning tidbit below** 
 This book is sweet and adorable. I find myself carried away by the Designated Ugly Fat Friend, Bianca, the usual teenage problems she confronts with and I find her escape of those to be a hell of a super exciting hot and wild one. Despite the imperfections that were already imprinted on her mind ever since forever, even more so when she was introduced by the word DUFF, which was implied to be her by someone, she actually coped with it so well no matter how that word bothered her so much. I especially adored her snarky and practical personality. Her cynicism doesn't even annoyed me a bit and I like her for having that. Reading Duff was a fun reading experience. Another great chick-lit experience that you wouldn't want to miss out on! 
 **I warn you though, there are a lot of sexual innuendos here so don't just limit your expectations based on the cutie title itself** =)
