"However, it is not good to use impolite words to describe something"
CBD my point was that the words are not impolite to the majority of people who use them for reasons other than to insult. Those words are becoming commonly used and will most likely eventually be adopted into the language as regular words.

I am very hungry
I am f*****g hungry

The most common usage, as I said before, is to provide emphasis. If you are offended by that sentence, than you are attributing a meaning to that word which was not intended. Although language seems like it has a static existence, it is actually always evolving and adapting to fit the language requirements of the society it exists in.
