Ron Jon 

A sexualy manuever whereas a man stands on the back of his partner, as if surfing, and masturbates. To successfully pull off the Ron Jon, the man must ejaculate before falling off his partner's back.

I'm going to try to give her a Ron Jon tonight. Wish me luck!

Ron-Jon Effect

When you've heard a story so many times that you feel like you were there, and therefore have the right to tell the story as if you were there.

After hearing about what happened at Ron-Jon so many times, Jimmy became a victim of the Ron-Jon effect

Dirty Ronjon 

When one removes the seeds from a jalapeño chili, and inserts the tip of their penis to use the jalapeño as a condom. The Dirty Ronjon is frequently combined with a duck and lamb grease lubricant, and sous vide shrimp aromatherapy for maximum romantic effect.

My booty is still on fire from getting a Dirty Ronjon for our anniversary last night.

RonJon 

An Asian man who goes my the name of John, or ‘jon’

“Hey, who’s that Asian dude?”

“I think he goes by John or Jon”
“Oh yeah! He’s a total RonJon.”
