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.
I was banging Gertrude from behind, doing some California long stroking, when I pulled it out too far and mis-judged my re-entry. Much to her shagrin, my meat missle lodged itself in her poop chute, and she gave me the 'ol Fish eye!

During sex, while working from behind, you shove your finger in her pooper. Thereupon, she turns around in a one-eyed winking motion to see what the hell you are doing.

when doing a chick "doggy-style", you quickly, and without warning pull out of her vag and shove it into her ass in one stroke. she will then turn around with large bugged out eyes at the shock. and, if you manage to catch your finger hooked in her gaping mouth during this, you've completed a fish-hook.
i was doing my girlfriend the other night, gave her the fish eye, now she won't let me do her from behind anymore

From behind, you shove both fists in her ass (or his if in prison). Thereupon she turns around in a one-eyed winking motion signaling that she has been there and done that.
