lava turds 

Liquid shit that is so hot it oozes out of your ass like lava.

After eating the cheese rolls from Taco Bell, MArk had to drop off some serious lava turds.

lava turd

A crap so hot that it burns when it comes out and continues to burn after it's passed. Typically of the soft variety of poop.

Guy 1: "Oh man, I was just on the toilet and had a crap that burned so bad."

Guy 2: "Sounds like you passed a lava turd."
