i don´t think so, if you can comminicate, which i think everyone can do, then you don´t have to be educated just real, trust me if you use an "educated" word wrong...people will know, its better to say..
i keep not doing it

use words that you know knowing what big words mean does not make you tight.
the point is to say something i can, as a listerner, understand. be it simple regular words or bigger words..as long as you don´t change what you saying and putting big words wrongly.
