When a woman has such a nice ass that you want to ejaculate on it.
"That girl's got a jizz ass! I hope I can get with her so I can bust a phat nut on that badunkadunk!"

Coworker 1: Damn, that new girl, Maya, has an amazing body!

Coworker 2: "Hell yeah! She has a jizz ass! Maybe she and I will hook up so I can skeet on that booty!
