Shit volcano

May be used to describe a person or object that spews out excesses of crap in verbal or physical form.

Word derives from a combination of the relatively harmless cuss shit and volcano; which until just recently wasn't considered quite as negative a word as it currently is (post Icelandic volcano ash cloud malarkey).

Carl is such a shit volcano.

Hairy Volcano

When a woman with a hairy snatch stands on her head and squirts skyward.

Sad Volcano

I . When a male is engaging in an act of vigorous masterbation and is ready to induce a romantic explosion. However, the contents of the scene in the pornographic film unexpectedly switches to less desirable content after the masterbater has already committed to purging gametes. The resulting effect is the masterbater attempting to cease the ejaculation but experiences a low force expulsion of seminal fluid.

II . When a male is participating in sexual courtship with a female that is ravenously performing either oral pleasure, an eych-jay, or intercourse in an overly zealous manner causing the male to lose control of his mojo. The male tries to stop the sensation but is too late resulting in a low force expulsion of seminal fluid.

Note***
No orgasm is experienced during a sad volcano . . .

Examples:

I . Ya this one time I was watchin' a random video I found and it seemed legit so I took a gamble and committed before fast forwarding and then the scene switched to a zoom-in of some random guy beating off in the background. . . I tried to stop but it was a sad volcano.

II . Dasheekee was givin' me an eych-jay and then just stuck it in while we were watchin' Legend of the Hidden Temple on Nickelodeon but it felt too bomb so I told her to stop moving but it was too late . . . sad volcano.

Exploding Volcano

This is when three guys jizz in your butt and then you squeeze and all the jizz comes out exploding like a volcano.

Oscar let 3 guys jizz in his bum and then he bent over and did the exploding volcano.

Toilet Volcano

When you take a dump, then when done before you wipe you look down and you see a volcano reaching out of the water, like some majestic mountain in the south pacific.

"I must have eaten some bad bbq last night. This morning after taking my normal dump. I looked down and saw a Toilet Volcano, steam rising from the water. I reminded me of of the last time I was in Hawaii."

Popcorn Volcano

Jumping in your movie seat with a container of popcorn causing the popcorn to fly up in the air like a volcano.

While watching Halloween X there was a scary scene that resulted in several popcorn volcanoes.

Underwater Volcano

First, one must conduct the steps necessary to make the Alaskan pipeline viable (shit in a condom, freeze it).

The Underwater Volcano is when a female voraciously pleasures herself with an Alaskan Pipeline whilst in the bathtub and on her period.

Created by A. UoS 2015.

Dan: Hey Mary, fancy fucking later?

Mary: Sorry Dan, I'm on my period! I think I'll just give the Underwater Volcano a try tonight

Dan: No problem, I've heard the Underwater Volcano is a fantastic experience, enjoy!
