When
one sews up their asshole for 3 weeks in order to build up a significant amount of fecal matter. They then fuck someone'
s asshole, and pulls out to reveal a gaping asshole. They then unsew their
ass and shit into the gaping
ass, making sure to lick off any of the shit that misses and/or drips off. The gaping
ass is then fisted so that it gets pushed up through the
ass and then is vomited out. This vomit-shit is then used for urethral fingering lube. In order to prevent getting a UTI, both parties urinate out the vomit-shit, which is what is called "cropple juice".
