Slang words are still used today and there is a long list of words you can use. I think different slang words have rubbed off on adults because I hear more and more of them saying them. The slag I use and my friends use have rubbed off on my mother. She is starting to use slang more than me. Also my brother likes to rap so we both get a lot of slang from him.
I don’t think I ever heard one of my teacher’s using slang. I don’t think its professional for them to use slang while they are teaching, but I do think when they leave they use it. Everyone has used a little bit of slang throughout their life. I believe that slang will never go away, because it’s something we use to communicate with one another.
