Dirty Volcano 

Is when your partner takes dietary pills the night before, and she holds it in until you put your balls in her anus, and all the build up of poo and diarrhea pushes your balls out of her anus causing all of the poo and diarrhea to shoot out like a volcano.

Damn, last night we performed a dirty volcano, and its was perfect.

Tony - "I watched a great porno last night."
Ernest- "What was it?"
Tony- "Was normal at first then the girl ended with a huge Dirty Volcano. I fell in love."

The Dirty Volcano

When your partner is laying on the ground with only their shoulders touching, holding their legs to their head, while you proceed to have anal sex. Once you ejaculate in the rectum you grab their legs and thrust forward to the head making the semen shoot out of the anus like a volcano.

Friend: Why is the front of your shirt nasty?
You: Dude, I gave this chick "The Dirty Volcano" last night and she erupted on m shirt.
