A girl who is very independent. She's slightly dense and very self absorbed. Be careful when you get in a tussle with a Shannen because they are willing to go as far as it takes to hurt you, either physically or emotionally. A prime example of the adage, "never judge a book by its cover." Though Shannen's are usually very pretty, they are both underhanded, manipulative, rude, and just plain mean.
Carlos: I just met this girl, but we got in an argument and when she was arguing with me I felt like she was out for blood. I wish I knew her name so I could warn others to stay away from her.
Mali: Yeah, that was definitely a Shannen.
