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.

volcano

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."

volcano

When taking a bong hit, coughing back into the chamber, causing the bong water to shoot out, making a complete mess.

Damn... volcanoing sucks balls.

volcano

An opening in the earth's crust in which molten rock, ash, and gases are released.

I wouldn't want to live near an active volcano.

volcano

an act in which, when a fart is coming on, the asshole is elevated into the air either by situating one's self on all fours with shoulders to the floor or by lying on one's shoulders with knees to the ears, causing the asshole to open and remain so. once this state has been achieved, air can be repeatedly sucked in and blasted out, causing a signature sound that is difficult to replicate by other means.

I felt a massive fart coming on and was able to volcano for five minutes straight.

volcano

A sexual position involving at least one male. When the male is about to ejaculate, he lies on his back with his penis sticking up. He then shoots his load up into the air and back down. The other member of this sexual intercourse will then have the pleasure of watching the cum ooze down like lava or licking it off.

Beth's boyfriend was too fat to get off his back, so he just did a volcano and Beth just watched it ooze.
