Get the fish poke mug.
to poke a girl in her ass, generally to her enjoyment.
last night I was massaging Naomi's ass and I was spreading her cheeks, and she was just craving a good fish poke, so I gave it to her. And she said "oooooooooo".

For origins of this term, please refer to the Dutch version of the "Barbie girl" song, it is at the very end.
