A great singer and actress! Hilary Duff is funny, cool and soooooo good to watch. She might be a little bit fat but I think she's still pretty good the way she looks. I'm not a real fan of Hilary but I quite like the songs "Wake Up", "So Yesterday" and "Why Not" I think she's really good and I don't care if you think she's awful but I know that she rawx!

A Designated Unattractive Fat Friend, or a Dumb Ugly Fat Fuck- a duff is a girl who is the ugly chick at the party that would be a considerable hook up with a high amount of alcohol ingested. A duff^2 is the girl at the party who is so fugly that no substance in any form can justify a random hook up
Hey chris, michelle just showed up, but she brought 3 fucking duffs, jill, heather, and theresa.
-one bottle of tequila later
Tom - yo bro, heather is bangin
Chris - yea but shes occupied with mike, how does theresa look.
Tom - Fuck that bro, i wouldnt go near her with a ten foot pole, she is clearly a Duff Squared

A fake slutty girl who changed too fast. also lost weight much too fast when she HONESTLY didn't need to, and now looks like a skeleton. Disgusting. Used to be a pretty teenage girl, now a slutty, skinny whore.
If you watch any of Hilary Duff's movies (excluding Material Girls & Cheaper by the Dozen 2), she's a teenage girl who is the "goody girl" type. She has blonde hair in most of her movies. If you watch her "With Love" music video, she's a complete SLUT. She went through a change way too fast... you can see a really big difference in her appearance from Cheaper by the Dozen 1 to Cheaper by the Dozen 2. In the first one she looks like an average girl, with blonde hair. In the second one, she's a complete snob with nasty cheekbones popping out of her face and looks like a stick, also may I mention she wears too much eyeliner. She wears too much makeup all together.
