Cum Shot on someone's chest in the form of the Z from Zorro.
She wouldn't swallow so he blew his load on her chest. Did he at least onzo it?

The dude thinks he's a super hero in bed. Every time he has sex he throws down an onzo.

She freaked out about me blowing my load in her, so I just onzo'd her.

When something is on or when something is so on. When something is going to happen or happen intensely it becomes option to add the zo. It's commonly used when a guy thinks he going to score with a girl. Also used when a guy is about to fight another guy.
