The DUFF (2015)

A high school senior instigates a social pecking order revolution after finding out that she has been labeled the DUFF - Designated Ugly Fat Friend - by her prettier, more popular counterparts. When a smart high schooler learns she's the Designated Ugly Fat Friend in her popular clique, she enlists a jock's help for a massive makeover. Bianca's (Mae Whitman) universe turns upside down when she learns that her high school refers to her as a ‘DUFF' (Designated Ugly Fat Friend). Hoping to erase that label, she enlists the help of a charming jock (Robbie Amell) and her favorite teacher (Ken Jeong). Together they'll face the school's mean girl (Bella Thorne) and remind everyone that we are all someone's DUFF… and that's totally fine.
