When used in a business context.
noun: Churn is used when referring to 'churn rate'. Churn rate or churn, is the percentage of people that stop using or subscribing to a service within a certain time frame. For a business to be profitable, its growth rate must exceed its churn. As well as customer churn, there is revenue churn.
verb: These customers that have left have 'churned'.
Calculating churn can be simple. To find the percentage of customers that have churned, take the number of customers you have lost during a time frame, for example a month, and divide it by the number of customers you had at the beginning of that month.

The word of mouth crap that bubbles up in professional environments, some of which can be quite valuable, after sifted through, though typically ridiculed and scoffed at by everyone for its uncertainty.
Example of some churn: "Well, I have not talked to Rick, but Julie asked him when you were coming on board, and he said he would hire you as soon as we were sure that the new CEO will mean bringing in the business we expect."
