Volcanus

A particularly explosive bottom during a poo

Strike a light, my bum was like an erupting volcanus this morning! The minute my cheeks touched the seat,’BANG!’, there was brown lava spewing out of my crater. Good job I didn’t try and fart or I’d have got magma in my grots for sure!

Volcanic Cum Dump

When a womans ass gets completely filled with semen from a large group of men, then chugs a bottle og magnesium citrate causing her to expell all the semen like a volcanic explosion.

Dude! We turned a chick into a volcanic cum dump last night! A bunch of guys busted a nut in a chicks ass, then she chugged a bottle of that liquid stuff you drink before a colonoscopy, she violently shit out all that cum all over the place!

Volcanic Island

A quantity of feces the consistency of wet cement that piles so high that the peak of the mound breaks the surface of the water creating an island.

Man, that burrito from last night turned into a volcanic island this morning.

volcanic island

When you shit so much that it rises in a cone-shaped pile above the water in the toilet bowl.

Philip: "I ate so much El Pollo Loco this morning that I just made a volcanic island... it almost made contact!"

Volcanic Turtle

A freaking moron who likes Turtles but does not really like Turtles. This person is a queer and is obessed with Urbandisctionary.com. Has problems with his brain and likes to love himself, because he has noone else.

That freaking Volcanic turtle is a bitch!

volcanic explosivity index

Volume of products, eruption cloud height, and qualitative observations (using terms ranging from "gentle" to "mega-colossal") are used to determine the explosivity value. The scale is open-ended with the largest volcanoes in history given magnitude 8. TheVolcanic Explosivity Index (VEI) was devised byChris Newhall of theUS Geological Survey and Stephen Self at theUniversity of Hawaii in 1982 to provide a relative measure of the explosiveness ofvolcanic eruptions.
