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.

Corked Volcano

Shitting on a bleeding a vagina then shoving a penis in, and when you are about to cum, pull out and spray blood, shit, and cum all over the sheets.

"I gave Suzie a corked volcano last night, I guess I'll be doing a load of sheets tonight".

ass volcano

An ass volcano is the act of inserting baking powder, vinegar and red food coloring to a gaping asshole (normal it has been stretched out from a vigorous session of anal sex). Once the ingredients have been inserted you will have a grade 7 caliber explosion that even an all taco bell diet can not top.

Did you hear about that piece of whore trash Justin rammed the other night ? I hear he rammed her right in the ass and gave the cum dumpster a fucking ass volcano. I would makke the whore my wife.

brown volcano

when one defacates onto a females chest in between her breasts, then squeezes the breast together, thus forming the "brown volcano."

She'd recieved the angry pirate and the frothy walrus, but the brown volcano took the cake.

Upside down volcano

A rather graphic representation of a girl on her period.

Man, that girl was bleeding so heavy it looked like an upside down volcano erupting.
