You. Used in addressing two or more people or referring to two or more people, one of whom is addressed.

.2. y'all 659 up, 158 down
Southern 2nd person plural pronoun. Most concise and easily distinguished. Despite the assurance of some emails that have been passing around, "y'all" is plural. Only an absolute idiot would use it as a singular pronoun.
