I am so confused.....

We all know that the English language is

Well, for a lack of better word.. confusing..

Like the word HACK..  I have always thought

It was a bad thing..  meaning to break up things,

Or to get into one’s computer and make havoc.

Be a hack was not a good thing..

Now I see it used a lot.. It seems like it is suppose

To mean.. research something so you can use it?

Or what is online.. is

1. Definition of hack
   
   The link above goes to the definition page for "hack".

You got that?   Because I sure don’t.. I don’t know if it

Is good or bad.. sounds like it is mostly bad.

UPDATE... 
add to this .. DUBBING... which is a dance or stance... while bopping up and down... which a young man got into trouble doing at the Congress swearing in. 
It also has something to do with drugs as well.. so be careful how you use the term.. but I am still confused...
