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.

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."

The Madagascarian Volcano is a sexual act in which a Russian male stands a Madagascarian women on her head, pours various types of alcohol into her vagina and makes her squirt which then causes a massive eruption of female genital fluids as well as alcohol.
Yeah we performed the Madagascarian Volcano last night, subsequently she almost passed out for being in the position for too long.

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.
