Unicorn - Urban Dictionary Definition
That girl that you can't catch. Everything about her is so perfect (divine, if you will) getting with her is unfathomable. She is truly a blessing from God. Bumping into her on the sidewalk is a good day. Holding a conversation with her... you were probably dreaming. Anything beyond that - good luck. It takes time, effort, and a whole lot of persistency. But never give up; unicorns are said to be "uncatchable," but nothing is impossible. Impossible is nothing.
