A JanaLyn is a gorgeous girl. She has many talents that are overlooked by most people. Although she is pretty, she has a nasty temper. Unlike the rest of the world she does not think she is pretty. She prefers to spend most of her hours alone listening to music.
That girl is so hot that she's gotta be a JanaLyn
