A sex activity where you shit in the bottoms ass and wait for their body heat to make it boil thus making it flow out like a volcano.

You're giving him a hand-job. Just before he comes, you dip your other hand in the open jar of chili sauce and quickly change hands. He'll huff and puff just like a volcano, and when the sperm mixes with the chili sauce it looks exactly like lava!
My boyfriend try to do the Batman on me last night, but I beat him to it by doing the angry volcano!

The sexual act of a man covering his penis in frosting and pop rocks then commencing to receive oral from the female. Quite stimulating for both partners.

A very dangerous sex move. First, you take the onion volcano from a hibachi restaurant, put it on your companion's asshole. Then, squirt lighter fluid in their asshole and ignite it with a flame. While the flame is still burning the male inserts their penis into the women or mans asshole for a nice warm, burning sensation.

You meet a stripper in Vegas. You are banging her so hard from behind that when you cum she projectile vomits and fecal matter leaks out of her anal cavity onto your cock and drips down your balls.
