A girl who sleeps with (or at least tries to sleep with) a guy her bff is not quite over yet.

Sex kitten. Sunniva is an old Irish name which originaly means "gift from the sun". It was adopted by the norwegians after St.Sunniva came to Norway. In modern times however a person named Sunniva is often associated with a feminine, sexual and curvaceous woman. Sunniva can also be defined as someone who has a lot of sexual knowledge.
First Person:"Wow, look at that beautiful, curvaceous woman!"
Second Person:"Yes, she's a real Sunniva, huh?"
