If he samples piss you off, then PsyOpus is doing their job. They obviously set out to piss everyone off with the samples, further emphasizing the meaning behind the song. It's called 'Choker Chain' for a reason.
The weird samples almost remind me of a crazy ex. But then again, that's what I kinda figure this song to be about, being "Choker Chain" and some clingy whore repeating stuff. Good show, my ears and brain now hurt, bitches. XD
