The abundance of fecal matter that is held captive for such a long time in a person's body until it transforms into creature like beings. Overly constipated to the point of no return when alien like creatures start to seap out of the asscrack in determination to take over all of mankind's asshole's.
Dude I was so constipated last week that I farted and my ass creatures ran out for freedom.
