Jizzamatropolis 

A place a male goes to when the sex is so good and he's about to ejaculate. A land full of steamy ejaculate. Is said to be a mythical land but others disagree and believe this place exists!

Nigga, the sex last night was SO good I partied all night in jizzamatropolis.

Hey boo, you wanna go with me to Jizzamatropolis?

Jizzmatron 

Useful man-machine imported to a lucky lonely lady's boudoir. Aka a jizzdroid.

"We think we know the perfect bachelorette gift for solitary Martha," said Penelope, always down with the latest trends. "This dude is a regular jizzmatron. I've already placed the order."

"Covid layoffs left me without a job," said Howie the paralegal. "So I plundered the gig economy for work as a jizzdroid. Pretty sweet all around."
