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".
One who likes to take warm shit and squeeze itvigorously between his/her fingers, creating shitworms that spurt out onto the knuckles. "Cropple" is the light popping sound that the feces make upon being forced through the tight spaces.
"I hid in the backyard croppling dogshit all day."
"I'm a crap croppler, and I don't carewho knows!!!"
"Why are your hands so dirty? Have you been croppling crap again?"
