chuck hole gangster

The chuck hole being the hole in the door that you are served food through in jail or prison so you can be served while the door is still locked. A chuck hole gangster is an inmate that yells through the chuck hole about how bad ass he is but then can't back it up once the door is open.

Man I thought that black kid was probably very good at fighting the way he talked.....but when the doors opened we saw he was just a chuck hole gangster.
