Verb. While taking a hit of weed through a pipe or bowl, the stoner coughs. The term Volcano refers to the flaming herb and burning ash that is erupted out of the bowl, often burning holes in carpet or even pot head's hair!

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

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

-3/4 glass of sprite or 7up
-1 to 1.5 shots of vodka
-1/4 to 1/2 scoop of 'fruit punch' poweraid powder (amount dependent on cup size)

1) Pour sprite/vodka mixture into a glass or pitcher (if making multiple volcanos) 2) place powder into drinking glass 3) rapidly pour sprite/vodka mixture into drinking glass with powder

Once the sprite/vodka mixes with the powder the drink turns red and starts to fizz out of the glass, something of an eruption takes place. Yell VOLCCCCAAAANNNOOOOO!!! when the eruption begins. VERY messy drink to make.

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.

When you're leaned back on your shoulders with your knees behind your ears lighting a fart and diarrhea comes out after the fart, thus creating the eruption effect.

In order to be a true volcano all three factors need to be present. Gas, diarrhea, and lit flame!!!
