I don't know much about swearing word in English.

When I was reading books, I often met some offensive situation in the story and in that story people in the story said some offensive, swearing and insulting words.

But I didn't think that was pretty offensive.

People in the US were said that they are most offensive in the online and it didn't surprise me.

I can meet a lot of medias about US culture. Movies, musics and books.

People in the movies were always saying swearing words.

People says swearing words in Korean might as well be more offensive than any other countries'. Those seems to have more offensive and cruel expressions, but I believe that swearing words can be more offensive when those are used in the offensive situation or the person who used them via his face than what expressions it have.

I don't use any swearing words in common situation. but only use when I can use them to billians in our society and I can totally level with person I'm talking.
