New Lipstick Changes Colors When Ladies Are Horny

Science! That is what explains how Mood Swing Emotionally Activated Lip Gloss works, I assume. The makers claim that when a lady wearing it is in the mood for carnal pleasures, it turns deep red.

How does it work, you ask? By "reacting with a girl's body chemistry." Oh, I see, well that sure explains it.

And even if it does work, I'm not sure what the benefit is. I mean, do you ladies out there really want to show your cards that obviously? Whatever happened to the mystery? [The Sun via The Daily What]
