SLANGS

Why do we use slang words??

Can any1 tell me the answer to this simple question? Slang words can be used to emphasize an idea, or the validity of that idea.

Slangs can be derogatory and offensive to some, but funny and hilarious to others.
They are an important part of our daily speech and colloquial language. But it is often argued that it has a negative affect on society as a whole… i.e. a social welfare loss (an economic term I recently learned). I disagree with this point of view. I perceive these so called “slang” words as an important part of speech. They may be looked down upon by self-righteous “proper” persons, but even they are forced to use one of these at times of desperation or frustration. Many times, they can not express their annoyance in any other way and are forced to use these…. So, people, don’t look down upon slang. They provide (for lack of better terminology, because my brain can’t come up with anything better) a required release of anger/tension… without which, people would be worse off.
