Love Defined Mathematically!

This topic arose when a friend of mine made a generic statement saying mathematicians are too logical and it would be hard to define the term "love" mathematically. This is what I wrote out.....

Love is a universal language. It is both infinite and undefined!

What are your thoughts on this? This is simply a visual way to depict an emotion through a unique and fun method. That being said, do you think we could take this further and quantify abstract emotions and concepts using mathematics?
