A combination of a retard and Bevis from "Bevis and Butthead."
That guy is a total idiot, what a Reevis!
"Revies" is a common slang term used in place of the word "Reviews". It is used extensively among creatives and artists.
Dude 1:"Hey, have you seen the revies on the new iphone yet?"
Dude 2:"Yeah, I got to get that phone."
