The above question is what Justin asked me tonight. I was telling him how my cousin Elizabeth was catching some slack from the nurses at the hospital because she gave her son a binkie. He looked at me puzzled and stated "what the f*** is a binkie?" After I stopped laughing I explained what it was. He wants to know why I call it a binkie and not a pacifier. I really don't know. They have always been binkies to me. How about everyone else- Binkie or Pacifier?
