If you get some gross, unidentifiable substance on the bottom of your shoe, you can call it crud. Basically, crud is anything that's grimy or dirty, especially if you're not sure exactly what it is.
Other ways to say crud include gunk, slop, or muck. Your mom might complain that your room is full of crud, or you might spend a summer afternoon washing crud off your car. Either way, it's generally dirty stuff, bordering on the disgusting. In the 1940's, crud was popular slang that meant “nonsense or rubbish.” Earlier, it was Army slang for “venereal disease,” or sexually transmitted disease.
