Originally a Sparks song (eaten by the Monster of Love) "Monster of Love" is a personification of love, being represeted as a monster that eats people up, and spits out people with all the cliche signs of being in love (doey eyes, big grins etc.)
It ain't a pretty sight to see the way it leaves 'em
It chews them up and spits out creatures with those
Sick sickly smiles
It just isn't right
And my father said "don't worry, son"
But look at him, he should have run
Eaten by the monster of love
