talk out (the side of) one’s neck
v. phr.— «Fuhrman is a creature who seems invented to indict the Juice and engineer his acquittal. He’s a two-headed-talking-out-the-side-of-his-neck beast of the apocalypse, who brought new formations of knowledge and power to the table.» —“Bigger’s Got Bank” by Greg Tate Village Voice (New York City) Oct. 17, 1995.
