Coined by Nathan Rabin of the AV Club, this is a free-spirited, quirky girl who teaches male characters in romantic comedies how to embrace life and love. She usually quotes song lyrics and plays the ukelele. (See Natalie Portman in Garden State, Kirsten Dunst in Elizabethtown, Zooey Deschanel in everything...)
Tash is such a manic pixie dream girl. Yesterday she gave me a necklace made from Fruit Loops.
