You dumb-asses! h.n.i.c., or head nigga in charge, was made popular by morgan freeman (aka god himself) when he played Joe Clark in "Lean on Me".
Joe Clark: You've tried it your way for years, and your students can't even pass the State's Minimum Basic Skills Test. That means they can barely read! Now, they've given me one year to turn this place around--to get those test scores up--so that the State will not take us over to perform the task which you have failed to accomplish: the task of educating our children! So forget about the way it used to be. This is not a damn democracy! We are in a state of emergency and my word is law! There's only one boss around here, and that's me. The H.N.I.C.
Mr. O'Malley: H.N.I.C?
Ms. Levias: Head nigger in charge.
