Yo, I'm like coach hines
You fuck it up once and I give out an extortion

from Patrick J. Dimosthenis – Shadowboxin' Lyrics on Rap Genius

Meaning

Extortion means forcing someone into giving you something through threats. A bully who tells kids he’ll beat them up if they don’t give him their lunch money is guilty of extortion.
Coach Hines easily becomes upset by inappropriate behavior from unseen students during school assemblies and threatens to kill and injure them in response.
