look up any word, like sex:

An NBC Policy is when the host of a party has disallowed the entrance of beat chicks.

N.B.C = No beat chicks

Any beat chicks that do show up will usually be met with loud chants of "NBC NBC", at which they may be confused while they are escorted out.
WHAT? I thought we had an NBC Policy here. Tiffany and her friends are the definition of beat!
