Parasite -

I know you and you know me

It’s been quite a while

I hate you and you hate me

You followed me every mile

Parasite, curse, misleading star

That is what you are

In front of me, just like a lure

That is what you were

I bit you still, against my will

The bitter taste of rotten waste

I swallowed you, I made it through

Now this is the end of me and you
