A combination of "face" and "acne". When you hold a cell phone to your face, the screen gets greasy. When you a on the cell phone for long amounts of time, the grease is taken off, then re-applied to your face again and again. Therefore, there is an overly greasy square spot on your face, very prone to acne.
