What is [fancer]?
"fake cancer." Also known as a reason why people have to come home from college. A health condition in which a patient exhibits cancer-like tendencies but clearly doesn't have cancer, and the doctors have no clue what the hell is wrong with you
Becca: "Ugh!!! I hate my fancer! I'm so mad I keep having to come home to Boston from Michigan during my first month out here! I wish the doctors would just figure out what's wrong with me!"
Anne: "But at least we get to watch Nick and Norah's Infinite Playlist together! And hang out at the Y!"
