Rhino Geyser

When your getting head, and you cum while being deep throated, and she doesn't expect it and your cum squirts out her nostril.

I gave you old step mom a Rhino Geyser last night. Here's the video to prove it.

chocolate geyser

An effect caused by inserting "mentos" and diet soda up ones arse. Very distant cousin to butt chugging

Sideways Geyser

When you're drinking a liquid, someone tells a hilarious joke and you spit out all of the said liquid.

Timmy: Why doesn't Mexico have an Olympic team?
Joey: I don't know Timmy. Why?

*Joey proceeds to sip his water*
Timmy: Because everybody who can run, jump, and swim are already in the U.S.
Joey: BWAHAHAHAHA!!!....
*Water shoots everywhere*
The Next Day....
Timmy: Joey totally pulled a sideways geyser at the party yesterday!
Carl: No way!

Shit Geyser

a Shit Geyser is when someone has diarrhea, doesn't wipe, and then swiftly sits down, causing the diarrhea pooled in the ass cheeks to displace and explode out the top of their butt cheeks, resulting in a Shit Geyser

"give me all the money in the register or else I will Shit Geyser everywhere

Gladstone Geyser

When you have a female fill her mouth with diet coke and pop a mentos right before fellatio

Dude she gave me a gladstone geyser last night, it was incredible but I had to call a cleaning company to handle the mess. So worth it though.

Fremont Geyser

When you dont want to have sex so you use a crystal geyser water bottle and stick it where the sun dont shine for her enjoyment, must be intoxicated.

"Nah I didnt want to so I hit her with the Fremont Geyser." " You nasty bastard."
