Let me tell you, baby
And I hope you get it right
I'm the worms in your stomach
That you call butterflies

You taste so good darling
I'm gonna suck you dry

I want another sip babe
Of your juice warm and fresh
Your sweet soft skin
Is the reason I am rash

It feels so good, darling
Sliding in and out your flesh

The parasite-host-environment system is dynamic, with several points of equilibrium
This makes it difficult to trace the thresholds between benefit and damage
And therefore, the definitions of commensalism, mutualism and symbiosis

Become worthless

Just one last thing now
Have you got the clues?
I’ll sum it up now darling
As so to end this blues

See, I'm a parasite, baby
I need to live inside of you
