A mild dialect-in-writing variant of "just sayin'," a phrase that follows a statement or affirmation that might potentially give offense in order to defuse any insult.

Standard English equivalent = "No offense."
"You buzzed that guy in? Suppose he was some sort of murderer or rapist?"

"That so-called murderer and rapist just happens to be my brother."

"Jes sayin'."
