I thought that "shit" was just a rude way of saying "stuff", rather than specifically meaning fecal matter, due to how people say things like "I don't have time for this shit."
When I was thirteen, I thought that FTW stood for Fuck The World.
When I was eleven or twelve, I saw the live-action Smurfs movie and there's a scene where a human says, "Stop saying, 'smurf' for everything! I mean, what does it even mean?! Smurf! Smurfitty smurf smurf smurf!" and a Smurf replies, "There's no call for that kind of language!", so I thought that "Smurfitty" was a swear word.
Once, I was playing a video game and at the end, one of the other characters said "That was pathetic!," referring to my lack of effort.
i never heard the word before, so I thought "pathetic" meant "wicked good."
As a kid, I learned from a song that the French word "connard" meant "a**hole."
One time, when I was in school, I called someone a "connard" and the teacher heard.
The teacher sent me to detention, which led me to believe that all French words were swears.
And the ironic part was, it was my SPANISH teacher who heard and sent me to detention.
I believed the word “faggot” was a swear word until I was almost 18. Also, when I was 7, several people told me that “boring” was a swear word. I totally fell for it. The phase didn’t last too long. Maybe a couple of months.
My father convinced me that grawlixes (those "@#$%&*" symbols that sometimes appear in comics to represent swears) were pronounced "errr-rrr-rr-rrr-rrr-rrr-rr." Even though I'm an adult, I still can't stop pronouncing grawlixes like that.
I thought the C-word was crap.
I thought Gaston from Beauty and the Beast was a bad guy because his name had "gas" in it and that was a 'bad word.'
When I was six, I heard my grandparents say, "I'm getting sh*tty". I thought that meant they'd pooped their pants and burst into tears.
For some reason, I thought "relax" was a swear word.
I used to think if you said a bad word you would get arested
When I was little my mom really cracked down on swearing. She was very religious and said that when you swear, you're saying a mean thing to god and it hurts his feelings. So if I slipped up and said a bad word because I was really upset, I'd go and apologize to God. I also thought that if I didn't, I'd have really bad luck afterwards and in general didn't understand how that whole relationship with God works. When bad things happened, I though God was upset with me personally!
At one point, I though that "sorry" was a swear word. Whenever I was told to say it, I'd spell it out instead (S-O-R-R-Y), because I thought it would reduce the effect
I used to think that beet was a bad word because it had 4 letters!
I used to believe b*tch was just a regular word for a female dog because a book about dogs was the first context I found it in.
I thought the f-word was fart.
I used to think that the b-word was butt
When I was a kid I heard my brother say the word "motherfucker" so I asked him what it meant. I think he was worried about teaching me swear words, so he told me that it's what you call your mother if you love her. At the time, our mother was in hospital having her appendix taken out and a couple of days later she came home. I was so psyched to see her and just yelled "motherfucker!!" Gave her one hell of a shock.
I thought that if I ever swore, even saying "hell" while reading out a joke, I would go to hell forever. I believed this until I was 10.
