These often occur a day or so after ingesting large quantities of spicy food, such as one might do in a Habanaro Pepper eating contest, supplemented with the ingestion of large amounts of liquid, such as at a Habanero Pepper eating contest. The result is an unusually liquidy shit that feel like someone is blowing out your pipes with lava, (technically magma, while still in your rectum).
Needless to say, these shits do not invoke the normal feeling of self-gratification that comes with dumping one's load. On the contrary, it often leaves the shitter's asshole with a terrible burning sensation. This is complimented by the fact that, due to the highly liquid nature of the shit, it oftentimes takes half a roll of toilet paper to clean up the mess, leaving the user with a burning AND raw asshole, as well as dozens of annoying dingleberries. The shit is often discolored, and the aftermath is simply a disgusting pool of red or greenish-brown liquid in your toilet bowl. The stench, even with fans, can often last for 17-36 hours.
