I have to agree with you on this point.
Rockdrummer, just think on conversations where a word gets used in a slightly different context not normally used. Sometimes you heard it before and sometimes you haven't but you understood it's meaning. Some people will totally miss it as they probably weren't paying attention or couldn't follow the jump in meaning. What Interpretrator is getting at is that languages are dynamic entities and change happens all the time. Take the word "bad". In today's world there are several different meanings and the dictionary won't give you a positive definition but it has been used that way (I'm a baaaad dude!).
I think I understand what you are saying and it's slang that you speak of I beleive. Most of the time the dictionaries are updated to reflect slang. So lets take the word bad. Below is the definition that does include the slang usage as you mentioned. Note definition 10. I am open to the fact that slang is used but untill it's common knowledge, it is subject to mis-interpretation. I am not saying that my opinion is correct, but it's just how I view effective communication.
