What does your lipstick say about you?

The way we behave and talk always delivers something about our inner selves. There are hundreds of books written on body language, cutting down into every little move that you make. But, today I've come across something different. Apparently, the shape of your used lipstick says a lot of things about your personality.

I can relate to two of the categories: Slant keeps close to the original shape and Flat top. 

Which category does your lipstick fit in? Does it really represent your personality?
