I have observed a good number of people muttering "fuckfuckfuck" under their breath when nervous. It somehow seems to vent the frustration out, and calm the person down. Why does this happen?
I found a few articles such as this that describe how saying the word triggers parts of our brains and all that. But is there a any linguistic reason?
I have noticed that saying euphemisms such as "heck" or "fudge" also helps, but not as much as the f-word itself. Does this have something to do with the combination of a fricative and a velar plosive?
