swarf or cack?
I had to look them up.
Swarf: Material (such as metallic particles and abrasive fragments) removed by a cutting or grinding tool.
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 South Africa. Derived from an ancient Indo-European word, kakkos, cognate with German word Kacke, Welsh word "cach" and the Irish Gaelic word "cac" which means 's%it'. Dookies, caca, #2, stool, poop, nugget, dump, load, shart, poot, kitty-roca, squeezins, chocolate pudding, dung, excrement, cow pies, feces, meadow muffin, guano....
Is this correct?
