Box worthy

A measure of the attractiveness of a woman.

Explanation -- An attempt to have an affair with a smart, beautiful and awesome woman might lead to a downward spiral of divorce, financial losses, and emotional turmoil to the point where you are living in a cardboard box under a bridge. If that were to happen, would you look back on the wreckage your life has become and say, "She was worth it"? If that is the case, she is "Box worthy".
