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.

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!

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."
