Crusty Volcano

A rare phenomenon in which several pubic hairs erupt from outside and within the urethra during the ejaculation process. This serves as a primary breeding ground in which crabs, syphilis and AIDS may develop and/or regress. Causes uncontrollable itching and in later stages causes fuzzy discharge and erectile dysfunction resulting in permanently hairy spooge.

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!

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.

Cincinnati volcano

When you take a dump on an airplane toilet that is so big you gotta get up and take a look. In that moment of excitement, you forget to put the seat down and hit the flush button. The vacuum toilet sprays excrement all over you and the bathroom.
Hey Greg, did you pack an extra shirt in your carry-on? I just had a Cincinnati volcano in the bathroom.
