So much depends on the tone of voice, the body language, and the situation. Do <em>not</em> take the risk of assuming that a word is OK, just because you have heard people using it.

A great illustration of the situational aspect occurs in a famous 1902 novel, <em>The Virginian,</em> by Owen Wister, set in Wyoming in the 1870s.

Wister just uses dashes, but since it is 2020 I will use the actual word, "bitch." The narrator has been listening to a conversation.

<em>“I suppose you have me beat,” said Steve, grinning at him affectionately. “You're such a son-of-a-bitch when you get down to work. Well, so long! I got to fix my horse's hoofs.”</em>

<em>I had expected that the man would be struck down. He had used to the Virginian a term of heaviest insult, I thought. ...I marvelled.... Evidently he had meant no harm by it, and evidently no offence had been taken. Used thus, this language was plainly complimentary. </em>

Later in the same chapter, the Virginian is playing poker with a bad guy named Trampas who "does not like losing to strangers."

<em>Trampas spoke. “Your bet, you son-of-a-bitch.”</em>

<em>The Virginian's pistol came out, and his hand lay on the table, holding it unaimed. And with a voice as gentle as ever, the voice that sounded almost like a caress, but drawling a very little more than usual, so that there was almost a space between each word, he issued his orders to the man Trampas: “When you call me that, </em><em>smile</em><em>.” </em>

<em>....Something had been added to my knowledge also. Once again I had heard applied to the Virginian that epithet which Steve so freely used. The same words, identical to the letter. But this time they had produced a pistol. “When you call me that, </em><em>smile</em><em>!” So I perceived a new example of the old truth, that the letter means nothing until the spirit gives it life.</em>

It depends on culture. The same swear word being said in different countries could cause different consequences: from nothing to overreacting and even fighting. In some cultures swear words have no gravity while in others they are extremely offensive and insulting.

I find it more fun to try to come up with words that sound like swear words but aren't. Just changing a few letters.

How many words can be classified in 6 of the 8 or 9 Parts of Speech?

The F word can easily function as a verb, noun, pronoun, adjective, adverb, or interjection (6 out of the 8 or 9 Parts of Speech) (it isn’t used as a preposition or conjunction or article).

When I was in high school, I played a lot of billiards/pool/snooker.

There was one guy who tried to dress like and look like Elvis and every time he spoke, he used the F word.

No sentence was immune.

Now, I was pretty cool at that age, that is to say, I wasn’t a prude, but even I found his overuse of the word repulsive.

Swearing may be quite common in several languages and/or cultures, but it really isn’t necessary.

It can be off-putting, hurtful, disgusting, disrespectful and it can also demean the speaker’s reputation. 

Dan’s first sentence summed up what I was going to say. In one situation the non abbreviated words “You f-ing bitch get the f out of here!” would get a similar level response with a smile and a laugh from your friend at a bar, while the same sentence said with sincerity between two teachers at a school in front of students would likely get someone fired.
