Michigan Geyser

the act of putting mentos down somebody's asshole and then pouring diet coke down the asshole. Then a chemical reaction occurs causing a stream of fizz to explode out like a geyser.

Tyler: Dude i just totally gave Amanda a Michigan Geyser last night.

Muddy Geyser

This is when you cook for your girlfriend or wife and lace her food with a shitload of laxatives. Your then having anal sex with her and as your about to cum you punch her in the stomach as hard as you can. You cum in her ass then hold on for dear life with your cock still in her ass while her stomach just rumbles. You pull out last second and her ass then erupts violently covering the room in cum and feces.

My wife pissed me off on valentine's day so I cooked her dinner and gave her a muddy geyser.

Geyzer

A derogatory term for a promiscuous bloke/lad whose only ability is that of ejaculating.

Quite often completely docile, Geyzers are incapable of conversations that steer away from their central cause in life, ejaculating again and again in whoever and whatever is around.

Richie's been a proper Geyzer since he started taking them pills. He said once he's come, he has to come again and again.....

Circle Geyser

A difficult sexual maneuver whereby a female completes multiple back-spins naked while becoming so aroused as to cause a fountain like spray to emanate from her vagina. The spray should land in a perfect circle just outside the circumference of the back-spins.

Female military members must throw a salute just above the vagina during the maneuver to earn full credit.

Her Circle Geyser was so perfect, I threw a penny into her vagina and made a wish.
