To jizz in the shizz you must have anal sex.
Example: Oh man! Karen was so hot yesterday, i jizzed i her shizz, right before she took the kids. It was so great.
Person 1: Why were you late to work
Person 2: Nah fam I clapped cheeks with the sis and some fondue today, had to jizz with the wizz
Person 1: *Commits*
you: damn that guy can jizz.
your mom: the jizzer is a woman, don't be sexist women can have cocks too.
"would you like a jizzburger with a side of creampie?"
