I pretty much been swearing since birth. I never did swear in elementary school since it was age of tattle-tailing. Online though, language was fair game. My mouth was potty to the fullest when I was reviewing bad products.

Bintsy : i do not....well i do in my head but no I always make it sound empty when reciting lines though

Only when I am in a competitive mode do I swear a lot especially when it comes to videogames. I get so excited that I do touchdown dances when I win and swear up a storm when I lose but not like a sore loser but more of a playful loser.

I'll be honest and say that I swear casually... mainly as a verbal way of showing my reaction... I never use them in anger... Well it would be hard to as I don't get angry with other people.... (except on a full moon) 

I think I just use them freely as they are used in a normal standard conversation where I live 

Whenever I am annoyed or brought somewhere near the point of anger, I begin to curse. When I play video games, my swears start flying around, whether I am doing well or horrible. Just fell into the habit, I suppose.

When I was younger, I really did not curse much until a friend kept doing it around me. Eventually, I began doing it every once and awhile, though it came out pretty awkwardly considering I was not used to them.

Online, it is easier to suppress the need to curse usually, since I can always look over what I wrote before submitting it, though in cases of live chats, I am more likely to slip. I have begun incorporating other words to replace curses for me to help lessen my chances of getting in trouble for cursing. Dang, screw, "farfignewton" and "Google darn it!" have been in my vocabulary lately. These sub-words, however, sometimes get spliced with actual curses sometimes, making entertaining but still vulgar words. Not like my parents really yell at me for cursing considering I am an adult, but I still dislike cursing where it SHOULD be inappropriate.

I swear when I feel like it's needed, before I never used to swear.. but now I do, I honestly don't know a teenager who doesn't swear. When I started swearing it was around my friends and over the internet, then it grew into me swearing around my mother when I got upset or angry. I won't swear around my grandmother, or my great grandmother because they would smack me stupid. But other then that it doesn't really matter. Of course there are some swear words I won't say, and that I don't approve of so I don't say those. 

Once I used to swear like an old drunken sailor, but I try to keep my swearing at minimum nowadays. I stopped swearing when I realized swearing doesn't get me anywhere, I don't even swear at video games anymore. On a further note, I seem to have lost the ability to become angry for some reason, I think I'm a ticking timebomb for that reason.

The only time I swear or use foul language is in school. It may be a bit coincidential considering I go to a catholic school but I usually only curse around my friends. When I'm outside of school, especially around my family, I'm very careful not to curse, because my family doesn't know that I curse and I would prefer to keep it that way.

   I use to swear to all the time, But I have learn to  control it  when I am in public or on a messenger board like this
now it happen when I really get mad,  But I just take a deep breath  and remember what the marvel  hero Iron fist says

"Those that anger you, shall conquer you. .." 

What is Iron fist talking about is  If people can make you mad, then that have already won.

FrankThePunisherCastle : Its also loosely based off an old Sun Tzu The Art of War quote.

random side note
The art of war
I have been meaning to read that book, but every time, My Local media center or Library says that it is missing or stolen that, makes me
mad, So I guess I will have to by it at barns & nobles

FrankThePunisherCastle : Good book to read (can be applied to just about anything). Only thing I should warn you about.

Make sure you do research on how good of a job the translator did on translating it into the book. Don't buy one that was terrible translating.

I don't. It makes people mad if you do and it sets bad examples.

I don't think cussing is particularly bad.
But its not good. Not something you should use in slang. (which I tend to do by mistake.)
Younger children shouldn't cuss, I think. But they do anyways, and we cant help that.

Swearing to adults though is rather disrespectful. So I tend not to do that to my mom or elders. Hearing my friends cuss Is different I suppose. But I get a bit irritable when I hear friends cuss to their parents and elders.

But that's there way of talking and not mine.
So don't worry about others, is what I suggest. (though it may drive you crazy.)

I don't swear, unless I'm with my closest friends and they've done or said something really funny, but I only do mild swearing words (in Filipino) and I never cuss when I'm upset, mad or irritated.

most of the time when I'm hanging out with friends, but sometimes I curse out of frustration or anger

I do swear occasionally, but only swear when my expression of anger/pain matches the degree of the word.

S*** or god-d*** would be for a really bad cut, or finger smashing type pains.

the f bomb would be reserved for serious injuries, forgetting something very important, or injuries involving copious amounts of pain.

I have replacement swear words which aren't considered swear words too.

Yes, occasionally, but not at work.  People get less and less tolerant of it in the workplace (I think). 

Almost never, I would say. I sometimes slip up rarely when I hurt myself, but even then its rare.
