Pronounced "See-Daf". Stands for "Can't Do Anything For Herself" and was created by Lynn, Stacey, and Jessica in junior year English for their friend Lindsey, who usually depended on her friends to complete her schoolwork. The name still applies to her now.
Lynn: "Lindsey asked me for the Vocab words today...She's such a CDAFH!"
