A girl who lives in a fantasy world, usually her bedroom is decorated in a fantasy theme, has excessive fantasies about guys in bands, actors or other fantasy figures who she will never meet, spends excessive time online living her 'life' on social networking sites or 3D virtual worlds or blogging. Wishes she could become her avatar. Her fantasy world is more satisfying than reality.
One girl to another: Jessica is becoming like a hermit.
Another: I haven't seen her in forever.
Girl: She messages me thru Myspace, she never calls anymore.
Another: She texted me that she found her soulmate on Second Life.
The best thing you could imagine because Pink Fluffy Unicorns Dancing On Rainbows are things only seen in dreams and sometimes TV shows and films. They are quick, smart, loyal and fat.
Pink Fluffy Unicorns Dancing On Rainbows is my favourite YouTube song.
