The act of shitting on your partner's chest, ejaculating on the pile of shit, using the penis to mix the shit and semen, covering the penis in the mixture, and then penetrating your partner in all of their holes. Generally considered extremely sick in nature. A personal favorite of Hollywood actor John Cusack.
I Karl Blankenshiped your girlfriend and your mom last night. So did John Cusack.
