the southern form of "YOU GUYSSS"

A southern contraction turned into a pop culture slang. To people in the south "yall" is used to distinguish themselves as southern so not to be confused with New Yorkers or otherwise "Yankee bastards" despite the obvious distinction in accents. In the north "yall" is used as a comedy staple to stereotype what yankees refer to as "idiots" and otherwise "ignorant rednecks."

In popular culture, "yall" carries the same stereotype as the northern taboo only it grants several comedians the ability to mock and otherwise satirize their own culture such as Larry the Cable Guy and Jeff Foxworthy.

All of you. Used when adressing someone or something

A way southerners say "you all" but it's much better and cooler.

Southerners originally invented the word, but now it has been copied by rappers, because even they know it's cooler (rappers are dumbasses.)

northerners consider themselves better, and smarter than southerners for not using this word, but all that not using it really does is makes them seem like
nerds/douchebags.

A mumbled slang way to say 'you all.'

Yalling is the act by which a non-southern person offends someone from the southern United States by teasing their speech patterns. Deliberate or not, yalling implies that the southerner is acting like an "ignorant redneck" which is an image many educated people from those states consciously try to avoid.
