Not sure if this counts as swearing per se, but we used to evolve new words and expressions all the time. For instance, back in the early 90's there was a singer in the UK called Chesney Hawkes, who was basically nature's last word in flop-haired pantywaists. We started using his name as a general all-purpose curse word and insult. Couldn't get the lid off of a jar of pickles? "You total Chesney!" Lost something? "Where in the Flying Chesneys are my car keys?"
