A unicorn is a extremely attractive man/woman who is dating someone who is way less than average looking. The term unicorn is used to describe it because, 1) it was some magical/mythical shit they got together. 2) there is no way it will ever happen again (once in a lifetime type thing) 3) the extremely less than average looking one will never do anything to lose his/her unicorn.
That's a unicorn
