A pretty girl who does'nt like to smile. Usually caused by a traumatic upbringing and/or bad relationships where she was taken for granted. Because of what she's been through, she does'nt realize how truly attractive she is or does'nt consider herself attractive anymore. A prime example of damaged goods.
Guy 1: Why does'nt the cutie that works at Starbucks smile more often? A pretty girl like that should be smiling all the time.
Guy 2: She's a mona lisa, bro.
Guy 1: Well, there's definitely a special place in hell for her ex boyfriends.

"Good from far but far from good"

a woman that is attractive from far away, but upon closer review turns out to be the total opposite.
This cute girl was looking at me from across the room, but when I went to go talk to her it turns out she's a mona lisa. Also, I'm a sexist dickhead.
