How it's used
Refers specifically to illicit or uncensored adult content that bypasses the official Hong Kong film classification system. While the term plays on the official rating system, it is strictly informal and carries a illicit connotation. Be aware that it can also refer to high purity heroin in criminal slang, though context usually makes the intended meaning clear.

Common mistake
Do not confuse this with the official film rating system. Hong Kong only has three official categories, so calling something a four is a way of saying it is beyond the legal limit of what can be shown in cinemas.
