Hillary Duff

A big fat dork who dates Joel Madden from Good Charlotte (the most awesome band on earth!!!) and thinks she's now punk. But other than that she really is a dork. She needs to go back to the whole I-can-act thing and make millions of dollars. I can't see why people like her but they do.

Person 1: Hey can i see you cd's?
Person 2: Yeah sure.
Person 1: Oh My f***ing God you have this really crappy Hillary Duff CD? Why in the Hell did you buy this?
Person 2: i didn't buy that my sister did (Her eyes rolling, bitting her lip)
Person 1: nice Good Charlotte CD though!!!

DUFF

DUFF stands for: designated ugly fat friend. A DUFF is typically hanging around the group of pretty, superficial babes. People who see the DUFF usually wonders why she is being seen with such hot chicks. DUFFs never get ass. DUFFs have never had a boyfriend. And DUFFs spend their friday nights masterbating.

Tammy is such a prep.
DANG, Felicia is looking fine tonight.
Lorena adds that latina spice to the group.
Erica is a hot cheerleader.
and then theres Marissa.
Well, every group of girls has to have their DUFF...

duff

n. an inert substance used to dilute a narcotic such as cocaine.

The substance must be similar in appearance to the narcotic so as to satisfy the suspicions of the narcotic purchaser. The introduction of 'duff' to a narcotic increases the profit margin for the seller if the selling price of the product is not adjusted for the amount of duff introduced.

See also cut

"This shit isn't anything but duff!" A phrase one may use when the narcotic purchased for one's pleasure does not administer the desired effect.
