I used to swear a lot. I decided to not swear at all (except for possibly mild swears), instead replacing most swears with minced oaths.
My family is Christian and I would get yelled at for swearing even if it just slipped out. So far, I don’t swear unless I’m feeling a strong emotion or acting impulsively, but I’ll usually say things like “F/eff” or “fudge” instead of the F-word.
I like to be “creative”, so my go-tos are usually “Go fudge yourself”, or “What the cluck?”
I might say “mother lover” instead of MF
When I was in high school, I was very anti-authority and swore all the time to be “against the man”. When I started working in day care I had to cut out all swearing all the time because it was too automatic to ONLY stop in front of kids. When I got a real job, I continued my no-swearing bend as a general rule because – at least until you get to know the people around you – people will treat you with more respect if you don’t sound like a foul mouthed low life.
Swearing all the time for no reason is a very low-rent affect. Letting out a rare swear will add considerable emphasis when your peers know it is not your normal behavior. Always swear when you hurt yourself. It helps.
