Mona Lisa Smile

That look on a girls face when you cum on her tits. Not a full on grin, but just a subtle smile that you aren't sure what it means, but you think she's enjoying it.

Sherry gave me her Mona Lisa Smile when I came all over her tits, but it went away after my buddy Tim nutted all over her face.

Mona Lisa's remorse

The feeling of a strong connection or bond between yourself and a piece of artwork.

How did the art deal go?
It didn't the guy had Mona Lisa's remorse.

Often art investors will refuse to sell a piece of art due to a personal attachment regardless of the profit from the sale.

Mona Lisa handshake

A Mona Lisa handshake is when you put your fist in a woman’s asshole and your cock in her vagina, then give yourself a handjob.

Last night I gave myself the best Mona Lisa handshake I had ever had!

Mona Lisa Smile

After you cum you take the residual cum on the tip of your penis and apply it like lipstick to your partner's lips.

"Wow, Sam's lips look really shiny," Friend 1.
Friend 2, "Yeah, I just gave her a Mona Lisa Smile."

Mona Lisa cleavage

When a cleavage looks kind of perky and happy but also a little on the sad any unperky side at the same time.

"Have you seen Emily's breasts? Her tits are like "Wow!" but also kind of "Meh." at the same time... I feel like her cleavage is somehow smiling at me--but also frowning at me! It's like she's got that whole Mona Lisa Cleavage thing going on. You know, like auntie Sara."

Mona Lisa Principle

The notion that while there isn't necessarily something wrong with someone/something, the two elements aren't a match.

"Dude, why did y'all break up?"
"Classic Mona Lisa Principle. She was beautiful, mysterious, and intriguing, but (pointing to my brain) didn't match a damn thing in my house."
