Learn the lingo with a new extended TV spot from CBS Films' The DUFF. Don't miss the upcoming comedy starring Mae Whitman, Robbie Amell, Bella Thorne, Bianca Santos, Skyler Samuels, Nick Eversman, Allison Janney, Romany Malco & Ken Jeong, which opens in theaters on February 20, 2015. In case you're wondering what exactly constitutes a "DUFF," Robbie Amell's Wesley explains that it's not a literal term, meaning one doesn't necessarily need to be fat or ugly to be considered this four-letter word.

Bianca (Mae Whitman) is a content high school senior whose world is shattered when she learns the student body knows her as The DUFF (Designated Ugly Fat Friend) to her prettier, more popular friends (Skyler Samuels & Bianca Santos). Now, despite the words of caution from her favorite teacher (Ken Jeong), she puts aside the potential distraction of her crush, Toby (Nick Eversman), and enlists Wesley (Robbie Amell), a slick but charming jock, to help reinvent herself. To save her senior year from turning into a total disaster, Bianca must find the confidence to overthrow the school's ruthless label maker Madison (Bella Thorne) and remind everyone that no matter what people look or act like, we are all someone's DUFF.

Check out the extended TV spot from The DUFF, directed by Ari Sandel, and based on the hit novel by Kody Keplinger. Stay tuned for more footage as we get closer to the adaptation's release in just a few short months.
