What is Pedigree Chum?
1.
The floating remnants of a particularly large and buoyant panful of excrement. As a defense mechanism, the faeces disperse into smaller chunks when the flush is deployed, surviving to haunt the bowl for the next unfortunate soul to encounter.
Simon: Who was last in the toilet?
Chris: Why?
Simon: There's a load of pedigree chum floating around the bowl.
