Why do people swear?

I swear when I feel that normal words will not express the emotion I am feeling at that moment as well as swear words would.

CAUSE THEY CANNNN!!

I swear only around friends, mouth them or in my head

Maybe because sometimes normal words can't convey feelings of anger.

It releases a lot of tension. I swear like a sailor, but I wish I didn't. I'm an intelligent person, thank you very much, but I'm also emotional. Swearing is just my natural response to frustration which, at school, is constant.

Bc sometimes people think "oh shit" and they just wanna let it out , man.

Actually, I hear that you feel happier after you let your frustration by swearing.
I'm just going to say, I swear a a lot because I'm Irish. 0u0

its weird but a cold way to express anger and frustration

People need a way to express anger and a mature way to do it.

^.^U Me neither...I hate swearing...But, I think there are a few reasons why...-

1. Basically, they're just too dumb to figure out a way to insult a person.
2. I think they curse just to appear as "cool". I used to do that(WHEN I WAS LITTLE; I WAS NAIVE BACK THEN) to appear cool to my friends but all I got was trouble.
3. Maybe because they're just super angry. My mom curses while driving. :/
