80's Rumble Geyser

The art of spinning on one's head, like the break dancing move, while having explosive diarrhea.

Spewing your poop upon everything around you while being popin' and fresh.

Someone made a mess in my room. It's like someone did an "80's rumble Geyser" in there.

Most likely. I did one this morning in the McDonald's bathroom.

Arctic Geyser

A sexual move in which liquid nitrogen is inserted into ones anus and in response, they fart out a large cloud of cold air, kind of like a geyser.

Person 1: “Yo dude what’d you do last night?”
Person 2: “Oh it was amazing! Me and my girl tried the Arctic Geyser.”
