So how i learned about swear words was through kpop.
When i was in 2nd grade we had this talent show and theres a group of girls who i was friends with wanted to do a kpop dance and the song chosen had a fistful of swears. My best friend at the time, who we'll call evelyn was just like "wow this is bad" but i was completly oblivious about it since i didn't know about profanity.
Now some time later we were talking about the song.
Evelyn: yea theres like the f word
Me: oh, you mean fuck?
Evelyn: 👁👄👁 ..... dont say that
...
And i said it so loud and clear thank god the teacher wasn't there.But yeah years have passed and now im the biggest swearer i know.
