y'all best break y'all selves 

Warning to children or other misbehaving persons to behave in public. Contrary to previously attributed gangsta use, it's what your Grandma would say if you and your cousins were acting up outside your own house or backyard, even if you were only in the front yard. Short for "Y'all best break y'all selves of actin' out, before I break you of embarrasin' me in public." Complimentary phrase might be "Ah'mo (I'm going to) take you right out this world and tell God the gators got you."

"We at the courthouse, y'all best break y'all selves while I pick up these license plates."

y'all niggaz 

Blanket term used for addressing other inferior parties in hip hop parlance. This does not mean any person qualifies for inclusion into "y'all niggaz"; rather, only external persons also a part of "The Game" but not in the immediate posse of the user and therefore inferior by extension are to be addressed as such.

Lil Jon: "We runnin this bitch, y'all niggaz ain't shit."
