A sexually indiscriminate woman; a slapper. A conflation of the word jizz with '-oon', to evoke a spitoon, as it were, for glob. Like the cuspador, a place you can release problem fluids where spitting them at the wall isn't a graceful option.
I found half a dozen foil wrappers and a pack of gonorrhea pills in Trish's handbag again. That bitch is a Forrestal-class jizzoon.

a cup that you whack it into. The cup is meant to catch the semen so that it won't make a mess when you finish. It's a spitoon for your cock what more can I say.
Welp. It's time to shoot some globs of glue into the old jizzoon.
Jizzoon: oh my god please just fucking kill me already
