The Fish Eye 

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.

I was surprised when kelly winked the fish eye at me.

giving the fish eye

Staring at someone without blinking with an annoyed or incredulous expression

Bubba said something really stupid, and I just stood there giving the fish eye to him (staring, not blinking)

Fish Eye and the Dolphin 

When Doing a girl doggy style and you attempt to put it in her bum, she looks back at you with one eye (like a fish) and goes "ah ah ah ah ah ah!" (the dolphin)

its pretty self explanitory dude!
