Get the poly pocketer mug.
An attractive female or male that enjoys playing sexually with people that are married but non-monogamous or polyamorous

A fun plaything.

If a particular Poly Pocket happens to be a young, attractive bisexual female who dates entire couples, she would also be a unicorn
We have a dinner date at home tonight with my favorite Poly Pocket, my wife is excited.
