Nope, the opposite for me. There are several studies linking the use of profanity with higher intelligence, contrary to the arguments made by mostly religious types who think it's a sign of limited vocabulary.
I think those studies are joke. I lean towards the religious types beliefs at 60%.
It is a turn off for me. Maybe one per day when you have situation with yourself / partner but more than 3 swears a day... I question that with what heavy issues does this person have. Now it is okay to detox or purge for an hour swearing IF you are by yourself.
In high school there was girl who lived 5 houses over from me, we talk for a 3min, a few times but not really much she walked with her friend. Was sort of friends with my sibling because they were in the same grade and school, but sibling avoided her, different interest.
She always dressed sexy but had no money, and she would wear a skirt mainly from April 1 to Oct 31. Cosmetics and the works BUT her face she hides it with her hair because it was sort swollen, I think she slept on her face. She took general or applied classes, I think she did better than me in life because I think she became a hairdresser.
So one day she walked with me for 10 minutes - her friend absent, so was mine - She swore every other word. I timed her how many swear words and it was 60 words in 60 seconds. Yes she wanted to jump in bed with me, but I didn't want that swearing and she seem the type that would call the police if you dumped her and accuse you of something.
I did bump into her 20 years later from high school with her mom, ass got big, single and cosmetics and she didn't say hello. I was surprised to see her taller than me.
In adult hood I met some women that swear, I kept my distance no matter how free "it" was.
