A knife fashioned in prison using successive layers of phone book pages soaked in one's semen. A Jizz-Shank is made over several months or years, usually. It generally takes about one night for a layer to dry.

To suddenly thrust inside an orifice as the first hot load explodes out of the penis. Multi-jizzshank is to thrust inside multiple orifices as each ejaculatory explosion occurs.
Last night, after pounding that hot bitch for an hour, I jizzshanked her in her ass as I was cumming. It resulted in the hottest creampie I've ever seen.
