A Los Angeles, California, man says his mother studiously avoided swearing. Instead of a curse word, she substituted the word piffle, which was often even more effective than a four-letter word because it was so unexpected. Piffle is most likely onomatopoetic, suggesting a disgusted exhalation through pursed lips. It’s common in the United Kingdom, and figured in the title of the popular 2006 British television program about etymology, Balderdash & Piffle. This is part of a complete episode.
