What is Love?

Love.
What is love?
A touch?
A kiss?
A dance between a man and a woman?
Is it your heart stopping when he glances at you?
Or is it nothing,
But everything at the same time?
Is love just a word?
A meaningless word?
A word used in an attempt to express yourself?
Can someone explain it to you?
Can it be used in logic or science?
Is love just a frivilous....thing?
A trick of the mind?
What is it?
What is love?
