Volcanic Soft Serve 

A shit that looks like soft serve ice cream that is so large in volume that it actually sticks up out of the toilet water forming a volcanic like peak.

My stomach hurt so bad from eating those burritos, I sat down on the toliet and made a volcanic soft serve.

The worst kind of volcanus is when you explode from both ends at the same time.

It’s also how Mauritius was formed.

volcanic crater

A sadistic sexual practice in which a male coats his penis in muscle-rub (a medicinal heat rub such as Deep Heat, Fiery Jack or Menthol-Balm) and then has anal sex with another person who is unaware that they are being injected with the muscle-rub. Within minutes, the recipient’s sphincter and rectum while become irritated and can be likened to a volcanic crater.

Dude 1: "Yo, I totally freaked out my girlfriend the other night!"
Dude 2: "How so?"
Dude 1: "I'd just come back from the gym, still had my Deep Heat in my pocket and gave her a volcanic crater for a laugh!"
