A girl that goes around kissing lots of boys randomly with no commitment to any of them. Like sleeping around but with kissing instead of sex.
- She kissed John AND Bill AND Bob in the same night?
- Yeh she's such a kiss slut

Get a kiss slut mug for your Facebook friend Callisto.
A female who makes out promiscuously, but will not go any farther than kissing.
That chick made out with twenty five guys last night, and not one of them got to feel her up. She's a real kissing slut.
