Cover art for The Crop and the Pest lyrics by Receiving End Of Sirens, The

I think this song is about a person who is a leech of sorts. A pest to a perfect crop. As he/she decays he/she attaches to someone who isn't and tries to take them down with them.

"I will treat you so well I'll take you up from this hell My gracious host, you're my lover won't you be my concubine?

The pleasure's all mine Your pleasures are all mine "

It's a broken promise, a lie of sorts. Promises and the pretense of love blind her as she becomes nothing more than a concubine to him. He's using her, once again, like a pest eats away at a crop.
