Such a large bowel movement that would overflow a toilet or container, so the person does it in their pants.
It wasnt long before the liquidy blibbit began to spill down their pants legs.

During the Viet Nam war a BLIBBIT was a large (50/100 gallon) stretchy container made out of heavy rubber that was used for transporting fresh water to recon troops in the deep jungle. Designed to be deployed by helicopter they were essentially huge water balloons and would occasionally burst when dropped from the Huey. When this happened the comic relief was appreciated almost as much as the fresh water.
Echo 1/7 reports that the blibbit burst when dropped from the Huey and completely fragged the LZ.
