A turd of unmentionable force or weight. The kind of thing that smashes any porcelain in it's flight path from your arse. Usually followed by a soaking of your Rusty Sheriff's Badge from the water that lies beneath.

A turd so large and dense it literally cracks the pan on impact.
You cant use that toilette, I just done a pancracker!
