Hey! All y'all! I disagree with Brian, but only because of a few punctuation changes that I would make that he didn't: https://en.wikipedia.org/wiki/Y%27all
Yes, for those of you who don't understand, this is sarcasm.
@Truman Overby using y'all is not really unusual. It is a contraction of you and all (sometimes combined as you-all) It is used as a (usually plural) second person pronoun. The exclusive usage of y'all as a plural pronoun is a perennial subject of discussion. Y'all is strongly associated with southern american english and appears in other English varieties, including African American Vernacular English and South African Indian English.<o:p></o:p>
