The fish eye occurs when doing a girl from behind, or doggie style if you will, and then suddenly and without warning, attempting, purposely or accidentally, to lodge it in her pooper. She will most certainly become wide-eyed and turn her head to look at you in horror. From your angle ou would only be able to see one wide open eye - resembling a fish eye.
