An affliction when everyone is seemingly drawn to Diablo Cody and you don't feel that she has the talent everyone else finds in her output. Can be used in relation to any artist you feel is seen through rose-colored glasses, but it is used best when discussing Diablo Cody.
Origins: When Diablo Cody not only won an Oscar for "Juno" but also began writing a column in Entertainment Weekly, Andy decided that everyone else had Diablo Cody-itis.
Usage: I just don't know what they see in that movie. Everyone must've caught Diablo Cody-itis.
First Used: The Curious Case of Benjamin Button
