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...
