A move performed during masturbation that involves the man jacking off and right before ejaculating the man ties a string right below the head of his penis and tying it so tight that it cuts of circulation blocking the ejaculation process. Then after 30 seconds while the cum is building up in the lower part of the man's penis, the man unties the string and his cum blasts out.

If preformed correctly the man's cum will look red like lava as a result of blood mixing with the sperm.

When one shits in ones mouth then punch them in the stomach region so that the shit erupts out of the mouth like a volcano.

1. A really good vaporizer that uses bags which fill up with vapor pretty fast. It's expensive as hell, around $500.

2. When a smoker coughs or laughs into a pipe or bong, making shit fly out of the bowl like lava out of a volcano.

3. An opening on a planet where lava comes out.
1. Mary got enough for a vaporizer!

2. God damn it, Jimmy pulled a volcano and all the bud fell out. ):

3. Hawai'i has volcanos.

Just like us, the very thing we dwell upon has pimples too. Volcanoes apear in many shapes and sizes on the face of the Earth with no clear way to dispose of them.

The greatest and best vaporizer in the world. Milks the vapor for you into a plastic bag, which is then inhaled through a mouth piece attatchment. The purest way to get high off of marijuana, other than eating it. Also used by some chefs to flavor food.
"Hey man, I got really high off that Volcano...almost, dare I say it...too high."

Volcanoes are just earth's dicks. They erupt after getting turned on for years.
