Hag-stone 

An incredibly hard stool, which is almost impossible to pass. So called either because it could only have been caused by witchcraft, or because it is so painful to expel that the sufferer’s face is contorted into a permanent grimace.

I barely slept - I was up all night with aching guts, trying to push out a massive hag-stone. I'll have to go to my GP if the suppositories don't shift it.

Thunder - egg 

A rock-like turd, or hag-stone which, loosened by a massive overdose of laxatives and/or suppositories, exits the bowel at great speed, accompanied by copious, deafening flatulence.

I need to get the plumber in. I was bunged up for DAYS so I took a handul of Sennocot, and shot out a massive thunder - egg. My arse was like a machine gun - I shattered the fucking toilet bowl.
