Fizzing

[Zipporah Schumaker]

The act of simultaneously pooping and ejactulating. Term comes from the combination of the words jizz and feces. This usually happens when something is so exciting and/or [arousing] that it causes one to not only ejaculate, but also shit oneself. [Fizzing] can often be accompanied by loud outbursts, [moaning], and hurried trips to the bathroom.
