Southern Living magazine once described "y'all" as "the quintessential Southern pronoun." It's as iconically Southern as sweet tea and grits.
While "y'all" is considered slang, it's a useful word nonetheless. The English language doesn't have a good second person plural pronoun; "you" can be both singular and plural, but it's sometimes awkward to use as a plural. It's almost like there's a pronoun missing. "Y'all" fills that second person plural slot – as does "you guys," "youse," "you-uns" and a few others.
