Magic Eye 

A girl who everyone knows is ugly but your friend spends so much time with her, that he begins seeing something that nobody else sees and thinks she is hot.

You: "Dude, what in the world are you doing with her?"
Friend: "She's really a nice, and pretty girl."
You: "Naw dude, sorry...Back up! You're too close! She's a magic eye!"
