Brendan was similarly amused, but brought up an interesting question: Is it the actual curse words themselves that provide the benefit, or simply the act of exclamation itself? We chuckled over the idea of vehement outbursts of "Butterflies!!!", "Unicorns!!!", or "Rainbow!!!"--words with traditionally positive connotations. But once we'd stopped giggling, I started to think about this idea in earnest.
For one thing, it isn't practical to apply cursing (in its conventional form) as a pain-reduction technique precisely because of the audience concerns I raised above. It isn't socially acceptable to go around muttering expletives under one's breath (and as far as I'm concerned, this is a good thing!). But there are other problems, too. Recent studies show that the more one swears, the less the pain-relieving benefits. Beyond that, even someone as curse-friendly as I am has to admit that these words have a negative bent that I don't particularly want to reinforce in my life. But it can't be denied that these words do express anger, frustration, or pain better than words like "Mermen!!!" or "Cinnamon buns!!!"
Enter creative cursing. I began inventing my own "cusses," with all the satisfaction of the hard, explosive sounds most expletives contain, but without the negativity they connote. And as I did, they started to morph and change into new words. It became a game. These days, I am constantly coming up with new nonsense curses, much to the amusement of myself and those around me. After all, who can really keep a straight face after a string of curses like "Punkmonkey!!!", "Crunchbubbles!!!", or "Punchbucket!!!"?
So go ahead. Cuss up a blue streak. And by that I mean, start with "Periwinkle!!!" and run with it.
