Slang words are introduced and do tend to evolve languages exponentially more than educated scholars revise or introduce new terminology in any official capacity. It's because of larger and larger groups of uneducated people using a language while having no clue that specific terminology already exists for what they want to express/say. So, they create their own "lingo" to put in place. Sometimes these terms take off becoming trendy, popular and ultimately commonplace beyond just their little group - it goes mainstream, essentially. Slang. It's absolutely a language evolution born of ignorance, and as history shows, we've just been okay with it after so long...or we weren't, and so those terms are not spoken/heard anymore at all....i.e. they don't appear in any dictionaries.
The reality is, yes, I have to just deal with it. We apparently all have to because the consensus isn't to be or do better. It's still ignorant and is insulting and annoying here and there for me, though, especially considering who winds up with a job where communicating highly important information, can't communicate properly to the rest of us. It's still quite stupid and dangerous sometimes, depending on whom you are communicating to. It can even lead to ignorance for future generations to believe, hold or cling to as any kind of meaningful occurrences. Communication needs to be precise or at the very least, precisely intended.
Prime example: I'm sure you've all heard the oft-repeated story of Marie Antoinette and that she reportedly said, "let them eat cake." And that's not the truth. It is not just a misinterpretation but a misreported (so called) historical "fact" of the account, as well as being not exactly anyone's best use of language that they would even think to say in the situation to begin with. Look it up. The real facts exist. After reading it all, think about if you've ever used this phrase, what you thought it was to all mean and if you did so for rather defense of your stance or actions....and now, realizing that you were completely ignorant and wrong. Think about what any ignorant words or actions anyone has ever done with this story inspiring their idiocy and such...and that if they just simply were educated and accurate instead, it'd have not ever happened. Ignorance of just a single word can create domino effects in communication overall that sometimes we can't undo, so I contend, the very least we should do...is care to not be ignorant.
