In a recent post, I said that part of opposing cancel culture is to rigorously define it. Greg Lukianoff, president of FIRE, took up the challenge. His definition, first mentioned in his book Cancelling Of The American Mind, is:

Cancel Culture is the uptick, beginning around 2014 and accelerating in 2017 and after, of campaigns to get people fired, disinvited, deplatformed, or otherwise punished for speech that is — or would be — protected by First Amendment standards, and the climate of fear and conformity that has resulted from this uptick.

When I talk about wanting to "rigorously define it", I don't just mean the kind of definition you would put in a dictionary. Consider the debate around the definition of "woman". It's perfectly fine for a dictionary to say "you know, female person, opposite of male". But the debaters want something you can use to adjudicate edge cases.
