Words are not words

We all use words regardless of their credibility of being actual words. I always thought words are words as long as they made sense and people know what you are talking about, you can't just go a round making up random words. If a word isn't in the dictionary is it not a word? People use them anyways, but why?

I feel like some people don't care if their word choice is proper or not they just say what they want. Other times words start going around, and we all know what they mean although they are not words from the English language. We use these words as a part of our daily conversations with people without realizing that they aren't legit words.

So is it wrong to use words that aren't in the dictionary? People say "ratchet" all the time although the meaning is different when we refer to someone as being "ratchet". We use that word all the time but the way we use that word isn't correct or proper. I saw a vine the other day of a boy saying "That was legitness". It made no sense but I burst out laughing because I knew what he meant. Everyone uses the word" bae" except it isn't a word. It is an acronym that refers to someone you "have a thing with". That sentence makes no sense but I wrote it anyways because it gets the point across. See what I mean?

I feel like it is okay to use these kind of made up words in SOME situations only. You can't go to a job interview and say that your bae recommended that you apply for that job and that is why you are there. However, when you are with your friends or people that understand what you mean when you say things like that then go ahead. You clearly make no sense but hey if people understand what you mean then say what you want... to certain extent of coarse.
