Many definitions for different kinds of poop have been given, as well as the slang names for those different kinds. However, one type has been forgotten...
The Meteor: AKA. "The Inferno" "The Napalm Rocket" "The Firelog" "Easy In, Not Out" "The Shooting Star" "The Ring of Fire" "Shitting Razors" "The Turdinator" or "The Hellraiser." This kind of poop only occurs under extreme conditions, and can be ranked by severity on multiple levels. The people who will experience this kind of poop are usually spice junkies or those with really poor indigestion.
This kind of turd is characterized by the unbelievable burning sensation it causes as it leaves the anus. Depending on how callused and experienced one's digestive system is, this kind of poop can be either runny or solid or even almost blockage-like. The degree of burn it can stimulate varies as well. A dinner consisting of mild Jalapenos or Italian Red Pepper Flakes, or poor indigestion that leaves some acid in your excrement, may create a slight stinging sensation, whereas the consumption of an intense amount of Habaneros or Ghost Chilies can bring tears to your eyes and force you to bath your ass in cold water for relief as you beg for mercy. In addition, depending if the spicy dish is accompanied by something meaty, cheesy, starchy, or greasy, this kind of poop can either be semi-odorless, noisy and smelly, or in the worst case, nose crippling.
"I love the spiciness of Thai Curry, so I don't mind the level of heat I poop out eventually."
"Oh God. I ate a Volcano Burrito for lunch this afternoon, and I'll swear I just shat a meteor!"
"I often compete in an annual contest to see who can consume the most Jalapenos in one minute. By now, I rather enjoy it. However, it's still easier going in than it is coming out."
"That Tex Mex we had last night was good, but I was shitting razors this morning."
