oyster

The part of the female genitalia that is comprised of the clit and the genital lips. When the lips have been parted, the lady's anatomy is quite like the appearance of an oyster.

Wow! Did you see the oyster on that chick in the movie? She had very large lips. And her oyster was very, very moist!

Oyster is London’s travel smartcard. You can put your Travelcard or Bus Pass season ticket on it, add travel value (cash) to pay as you go or have a combination of both.

Oyster cards are also reusable. This means that when your ticket expires you can buy another on the same Oyster card, and when your travel value (cash) runs out, you can just top it up.

I used my Oyster to get to work today.
