The reason "Spin the Bottle" and other kissing games are so popular is that they let you kiss someone without having to admit that you like the person you're kissing. You're kissing because you have to.

Kissing games are also a good way to try different ways of kissing. In "Spin the Bottle," a group of guys and girls sit in a circle, and take turns spinning a bottle. When the bottle stops spinning you kiss the person it's pointing to.
