a girl who is very good looking to the guy who is currently dating her - but quite ugly when seen by other guys. The guy dating this girl can see one way of the "optical illusion", but other guys see the opposite.

A Conversation:

Jim: Dude, your girlfriend is so ugly!

Dave: What do you mean?

Jim: I mean she's not attractive at all.

Dave: F*%^ that man, I think she's gorgeous.

Jim: Whatever, she's an optical illusion.


Dave: I see what you mean, Jim. I can see the other side of it now. She was definitely an optical illusion girlfriend.

Jim: For real.
