Sorry, I just feel like I’ve been seeing this a lot lately.
The word you’re looking for, my friends, is “chafe.” One “f,” not two.
This is just a public service announcement because I see it spelled wrong so often. If you say “chaff,” you are (unintentionally) talking about the husks and shells of grains that get discarded when they are being processed for human consumption, or the anti-missile countermeasures that aircraft employ to avoid being blown up. “Chaffing” is teasing or mocking, or maybe something about cryptography and encryption that I don’t really understand.
Chafe. Not chaff. Chafing, not chaffing.
