When I was in college with 4 other roommates we decided that we were swearing too much. So we made a pact that every swear word would cost 5c (this was many decades ago) and that when enough money accumulated we'd go have gigantic ice cream desserts. Three things happened. Casual swearing decreased. Deliberate swearing was born as in 5 words in a row, tossing a quarter into the kitty and saying "it was worth it". The third thing was a blooming of euphemisms. "Chomp on carrots", for example, replaced "suck my richard". The latter was followed by a discussion about euphemisms and we decided that if others did not think we were swearing, it was OK.
Even today many decades later, that experience resulted in me not doing casual swearing but when the situation truly warranted it I let loose with a few choice words.
I've also developed an appreciation for Shakespearean insults such as “Methink’st thou art a general offence and every man should beat thee.” and
“Out of my sight! Thou dost infect mine eyes.”
