She has a lazy eye. The reason she's been nicknamed "Wonky Eye" on FPH is because she's always hiding her lazy eye in her photos (something she has no control over and shouldn't feel ashamed of) but flashing her lard for the camera (which is something she does have control over and should be ashamed of). She was also featured quite often in Achtung's old albums. The irony and her frequent appearances lead to the nickname.
