We may refer to it as a “disqualifying comparison” - it lets us move faster down the search tree or move faster along the hash bucket linked list, until reaching the final string comparison in the search, keeping in mind that even the most efficient hash structure would probably waste a substantial amount of its time and cycles in string comparison.”

The term was coined by analogy with the relentless spiral of a nuclear winter: a chain reaction of pessimism in the AI community, followed by pessimism in the press, followed by a severe cutback in funding, followed by the end of serious research. It first appeared in 1984 as the topic of a public debate at the annual meeting of AAAI (then called the “American Association of Artificial Intelligence”).
