The Case for Cursing https://nyti.ms/2u1b173 in the New York Times lays out the magic that swearing at the most inappropriate moments can have for people.

Is swearing a ritual? Potentially. If in the moment of extreme stress or pain, the utterance of one of these forbidden words can be a release, that seems to be a small, meaningful, and transgressive ritual.
