Anyone know what this is called?

I remember two women sitting next to one another, talking. They were in bathing suits, saying how boring life is being "good" so they wanted to be "bad". They reminded me of barbie dolls. Dark hair, too. Their speech was very mechanical and they didn't move much until they decided to be "bad", when, if memory serves, then got on their knees to face each other. (some details could be wrong, tho.) I also remember them in a big feild, perhaps with flowers, shortly after this. Anyone recognize it?
