Katy Perry Chapstick

My heard a lot of meanings to the use of "cherry chapstick" in song by Katy Perry, I Kissed A Girl. Some are crude, and others are innocent. Tell me your opinion.

Yeah, I think it is lip balm that when you use your 5 senses, tastes a bit like the aroma of wild cherries. Hahahaha. :]

I do not think it is a metaphor here. It literally means the taste of her cherry chapstick ... but hey that's just my opinion:)
