If someone uses the word "whatnot" frequently are they pretty much always an idiot?

Question

What other words or phrases do you think make people seem stupid?

Answer 1

When I hear whatnot I think of an old person, not so much a stupid one.
Me, I hate it when people say "He don't" or "she don't", or "It don't" Many people do it and it makes me think that they are really stupid. I also inform them of the existence of the word doesn't.

Answer 2

idiot

Answer 3

like, you know, whatever
