'Plain right'

[Agnes]

Is the usage of the combination 'plain right' in a sentence correct? For example, "She is plain right stupid, period!".:?::-? Help please!

I've never heard that combination. In the case of your example sentence, I would use either one or the other, but never both.
"She's right stupid, period."
"She's plain stupid, period."

Thanks a lot SlickVic9000! I thought it sounded wrong too and guessed they meant to say " She is plain and outright stupid, period". But that would change the meaning in the sentence I guess.:-?

I agree with your assessment. In 'She's plain stupid,' "plain" is used to emphasise "stupid", but in the sentence in your quote, "plain" means something else.

I have never heard the combination (plain right stupid) either, but I have found it used on the Internet (which doesn't mean that it's acceptable, by the way). People seem to use this combination for a double emphasis. If something is "plain right stupid", it's even more stupid than something that is just "right stupid".
