The quality or state of being crappy; the degree to which something is of poor quality, unpleasant, or worthless.
Derived from crappy plus the -ness suffix (abstract noun formation), creating a formal noun from informal adjective.
Notice how we can formalize slang by adding -ness: the 'crappiness' of a situation can be discussed in meetings in ways that 'it sucks' cannot, though they mean the same thing!
