A name for a girl who acts unhealthily self conscious when she actually thinks she is the best. She uses her so called "self consciousness" to make people pity her and be her friend. Melanie is a name that when used in a sentence, instantly makes people want to vomit and then swallow that vomit over and over until they choke to death. Yes, not ALL Melanies are bad...but there are some bad eggs out there in the world who match this description. If you or someone you love know someone hanging around with a Melanie, please intervene and help save their soul from the blood sucking demon that is a Melanie. You could save a life.
