cack
(slang) faeces (feces); nonsense or rubbish: "what a load of cack" could equally be used to describe someone talking nonsense or as a criticism of something of poor quality. Also spelt "kak" as used in Afrikaans and Dutch. Derived from an ancient Indo-European word, kakkos, cognate with German word Kacke, Welsh word "cach" and the Irish and Scottish Gaelic word "cac" which all mean 'shit'.

I've also gotten the Scarfolk book, and it is genuinely a weirdly creepy piece of art.
