A girls/woman's name. This person seems to be nice on on the outside but vain on the inside. This person is usually very beautiful and has a perfect face,such as pretty eyes,straight nose,perfect teeth,hair. An Autumn cannot be trusted as she tells a lot of secrets,because it makes her feel important to others because she knows these things .She cannot resist feeling wanted and noticed by people.She usually does not respect what she has and abuses it and takes advantage of situations and people.An Autumn is known for being mischievous and not honest.She will not take the blame for anything for it will ruin her reputation and blames it on her friends or other people.The opposite sex cannot get enough of her and want to love her.An Autumn will usually have no self respect and realization of the world.
